I am an engineer and I am tutoring my son in physics and maths for his final year at A' level. It has surprised me regardless of using such equations as part of my work, how many of the basic principals behind them I have forgotten. This is a great refresher, and another indication that teaching people requires great thought and skill. Many thanks.
Hi, thank you very much for your comment. I started teaching quite late in my life, around 42 years old. I chose the level of end of high school / early university because I remember as a student, that was the hardest period in my student life. I was lost in physics and maths, although I felt in my guts that was the path I wanted/needed to take. Luckily I managed to get my baccalaureat with 50,04% haha, and then was blessed with fantastic and passionate teachers in my early university that helped me bloom up to the PhD... Of course, the first step in becoming a teacher was to study the current high school programs, under the angle provided by wisdom and serenity that comes with higher age. And, I had so many "haha moments" ! As an engineer , try it, you'll be surprise how much progress you'll make in your own field. High school content in Physics (and maths) is sooooo crucial, and when well understood, very powerful: the way it is approached by the teacher can shape the life and the success (or not) of the student. I remember the horrid and incompetent teachers I had in high school, that nearly destroyed me, and the amazing ones I had in Uni, that really cared... And from that defined my own approach. It all comes to the basics... Once a student understand the physics behind an equation, and can handle at least a little algebra, he or she can truly excel, and bloom. Once on the right intellectual path, there is no place that the student cannot explore by himself. That's why I made teaching my life...
@@PhysicsMadeEasy Thank you very much for your kind response. I enjoy maths and physics more now than I did when I was my son's age. The difference, apart from a mature outlook is, no pressure to pass exams. In my time, there was no internet but great textbooks which I still have. However, I did find the leap between A' Levels and university a very big one, and I really struggled in the first year of my Aeronautical enginnering degree. The amount of practicals, and subjects covered was overwhelming for me. After I graduated I decided to go straight to industry and I have had a great career in the aerospace, and marine industries. I would agree that teaching/tutoring is great fun but requires a lot of preparation and thought in how to communicate the information. It is not easy being a teacher in my opinion, and it is criminal that here in the UK teachers are not given the respect they deserve. Fortunately, I have the benefit of videos such as yours which I use as part of my preparation, and also for my enjoyment. I wish you health, happiness and all the best in your endeavours. Thank you for the knowledge.
You're awesome dude, I'm a medical student learning about electromyographs and this helped me understand a concept in physics which is a subject I'm not good at.
Hi Anas, I noticed with a vast majority oif my students that they didn't understand what an electric potential is... They get by, by following the rules, but as soon as they are faced with a slightly different problem, they are lost, hence this video! I am glad it helped you with your studies :-)
Most school textbooks tend to define electric potential the 'tougher' way around. "Potential is the work done.. blah.. blah." Is it necessary to complicate things this much? Why can't they write it the 'natural' way? Kudos to them for complicating a simple notion into an abstruse monster. And Many many thanks to the you, professor! This was a masterpiece!
I've been watching RUclips videos about physics since the beginning of high school and now I'm shocked that I have never came across to your channel before! Your explanation was incredibly helpful. Thanks a million. You kinda saved my life sir. P.s. I subscribed.
Hi Aysooda, thank you for your kind words. I am glad that the videos of my channel help you in your studies. Thx for subscribing. I hope you will enjoy the future content too :-)
I cant thank you enough for this very simple yet understandable manner of explaining . Teachers at school dont use analogies like and just rush in order to compelte the portions and never explain things this clearly. Thank you sir for this great way of explanation.
You are welcome. I know, sometimes under the pressure of the Curriculum, teachers forget to take these few minutes to explain basic notions in detail. It is a good investment to do so because it allows later in the program to go at a faster pace...
My view of voltage has forever changed, thank you so much for your explanation! I would not understand every detail on the first go but the picture you've left in my mind is priceless!
When i listen to him, i'm so moved by his humble way of teaching, where he can explain such complicated things in such a simpler way. such teachers are gems. cause all my life i only had teachers who used very complicated and hard words to explain things, it definitely is the reason why most of people feel so stressed with the subject. thank you sir, for changing my view of understanding physics.
Thank you Mahami for this heartwarming comment! Indeed, I agree, when a student understands his/her stress level decreases thus his/her health and quality of life improves. This is why it is really important for teachers to structure the ideas and make them easy to understand. We are a kind of doctor!
Thank you Aman, You know, I do not need to be overrated haha! As long as I unlock understanding blocks in many students around the world, I attain my goal.
I’m an undergrad taking electrodynamics, and after this video I FINALLY have a grasp about the potential! I honestly had a better grasp on electric potential than gravitational potential, which always confused me when it came up in classical mechanics, such as the explanation for Lagrange points.
Such an illustrative and simple way to explain something that seems so complex. Even a physics inept like me was enlightened, thank you sir keep up the great content
Hello sir ..i am from India .. studying in 10th grade ... I was not able to understand this concept.. .. but this video helped me ... Thank you so much
You are welcome Atul, I am glad my work helped you. In Grade 9-10, that is when a student starts to be confronted with this concept. If you continue in science, you will see the notion of potential showing up all the time, so it is essential that you understand it well as soon as possible!
Lucid, direct and clear explanations. Something to note about a common point of confusion is the difference in nomenclature between the concept of energy and work. This really helped to make that difference stridently clear and really helped to tie it all together Thank you Dr. Reny🙏
Hey John, thanks for noticing :-). Indeed, it gives a little air, to have these little interludes outside where what was seen is briefly summarized: It makes it more pleasant to watch, and in the end, might stick better in the viewers head. I should do this on more videos!
I wonder too... My channel is kind of a reaction to the hard time I had in High School. Still they exist: some lucky students are exposed to such teachers (I had some at Uni that took the time to make me bloom, and they became my inspiration)
I'm in uni and I've been dealing with these notions for years and it feels like I've never really understood them until now. Thank you so much what a great teacher!
Thank you Marie for your very kind words. If my video brought you a new understanding, then dig out your old school and Uni notes related to electrical sciences, especially those you are still fuzzy about, and rework them with that new understanding...Haha moments await you :-)!
Hi Paradox. You are welcome, and thank you for the encouragement! I am glad it helped you unlock the understanding of such an important concept in physics!
Amazing explanation and even more amazing visuals. Superb content. Please continue doing more physics videos! It is a massive help to students like me who self study!
Hello Malek, Thank you very much for your kind (and motivating) words. I will try to find some time for that. And I am super glad my work does help so many students around the world. Good luck with your studies!
Dear Dr. Reny, I really appreciate the quality of and effort behind this video ranging from the animations and intuitive explanations to even the changes in location while explaining said concept, as a student this really helped me grasp a vital concept i was unable to before. I thank you very much for making this video.
Hello Tango. Thanks you so much for your wonderful comment. I am glad my approach helped you understand and assimilate such an important concept. Review your previous class notes (those you took before you understood what an electric potential was), and reconstruct them based on your new understanding. Be ready to get crowded with 'ahah' moments :-)
Thank you! It's probably because I do not like having ads on my videos, thus, they are not promoted by youtube (Although I heard RUclips is going to force it soon)! Don't hesitate to share the channel link or the videos, so that others can enjoy some Physics fun!
With the gravitational potential, the potential will not be released unless there is an available path for the object to get closer to the ground. In other words, a ball stuck in a well won't spontaneously jump up out of the well to then go and roll off a nearby cliff. Why then will charged particles with an electric potential effortlessly travel in every possible direction through a labyrinth of wires to reach a lower potential (even if the path they take involves travelling in the exact opposite direction of the lower potential)? Do they just have way more energy than soccer ball in a well? Or what?
Hi Fletcher... A positive charge will never flow naturally to a higher potential, even if by doing so it would then have the opportunity to reach a potential which is lower. What you described here is called a potential barrier... Charges will not cross that barrier naturally unless their carrier is provided with a surplus of kinetic energy (like the ball in the well, will not naturally jump out unless pushed out of the well to overcome the potential barrier which is the depth the well). There is one exception though: the tunnel effect (Quantum mechanics), but that only works at a microscopic scale. Maybe you have an example that triggered your question? Or maybe you forgot that conducting cables are equipotentials (the electric potential is the same in the cable, whatever its shape...)?
Our whole nervous system and brain works because of local potential differences, that causes charged particles (ions and molecules) to move around and do what they are supposed to do. For example, me scripting and shooting this video, was a firework of electrical sparkles in my brain. I am glad that you experienced also such firework when viewing the video ;-) .
@@PhysicsMadeEasy I have a quick question. Let’s take a circuit, that has a resister. Let’s also say the voltage of a battery is 9V. Now all the voltage drop is across the resistor. Yet, the circuit keeps moving after the voltage drop.I don’t understand how exactly that is possible. If you have a battery of 9V and and voltage drop across a resistor of 9V, why does electrons keep moving. Would it have already lost all the potential?. A second question as well. When electrons go through a resistor, it loses kinetic energy by collisions with other atoms. Then how can the Amperage entering the resistor equal the amperage out of the resistor?.
@@MarkSmith-vo1vn Hi Mark, your confusion comes from the fact that you consider that the energy provided from the battery is transferred to the Kinetic Energy of the electrons… The energy provided goes to the Potential energy of the charges they carry. Through the resistor, it is the charges that lose energy. Just to give you a perspective. Mass of an electron: around 10^-30Kg, typical drift speed of an electron: around 10^-5 m/s. KE = 0.5mv^2, that’s around 10^-40J. Potential energy (= qV) of the charge carried by an electron, placed at a potential of 9V that’s around 10^-18J. That’s 10 billion trillion times larger. If you want, you can see the electrons continuing to move because they are just pushing each other like dominos… They are kind of “drifting”, hence the term ‘drift speed’. Ina circuit, the energy transfers relates to the PE of the charges.
@@PhysicsMadeEasy So all the kinetic energy gets turned into thermal energy. And The electron repulsion gives the potential Therefore the electrons have the same speed. So, then my next question is why doesn't electric potential decrease as you get closer to the protons. Is it because it is all relative to the electrons pushing it. I am kind of confused whether the potential of repulsion or the potential to go to the protons. Or does it balance out. The closer you get to the cathode the further you get from the anode.
Amazing! I‘ve tried to understand the voltage so many times through other videos, but you are the best I fully understand the voltage. Thank you so much.
Awesome you are the best communicator I have met and I am a professional civil engineer, but had difficulty understanding voltage. Thank you very much.
Hi there, thank you for your feedback. I am glad I could clarify this for you. By following rules, you can always manage without really understanding the physical concept behind voltage (tbh, I went through a large fraction of my uni studies that way). Maybe you can go back into passed projects where this concept was used, and see what you could have done better. I certainly did when I finally got it!
It Is unbelievable to see a professor like you I wasn't able to understand this as in India as many comments say don't have that good professors/teachers But Today I finally Understood the Concept Each Bit :D Another surprising thing is you are actually clearing doubts of Each guy in comment section as well ! Subbed and Liked The Video Sir
sir i got confused on this topic since 2 moths and i tried to understand the concept but i can't understand , finally today you have clear my all dought , thanks a lot
Hi Shambhu, I love reading these kind of comments because these reflect the exact objective I set for making these videos. Thanks for letting me know! It makes my day :-)
Hi sir, I am currently doing my Master in Electrochemistry and after watching this video I realized that until today I did not know what actually electric potential was. I am eternally grateful to you, keep going!
Hi Medina, thank you for your comment. I studied some electrochemistry at Uni, a hard topic but one I enjoyed because of it being so borderline between Chemistry and Physics. Then, when I worked as a researcher for a large company, I used my free research time to create an electrochemical lab because I was interested in looking at the impact of chemically induced films (oxides or organic) for the corrosion inhibition on various metals (in pipes for example). I was quite successful at it. The strange thing is that me too, I did not have a good understanding of what an electric potential exactly is. I had made my own idea, close enough for what I was doing, but when I reviewed the school physics programs before starting my teaching career, I realised I hadn’t really understood it. I wish I had, because it would have made me much more powerful in my research: I probably would have won a Nobel prize lol! I also realised that not many people do understand electric potentials. A friend of mine is an experienced electrician, working in that field for years. He worked the electricity of my house ( I paid him for that), One day, I asked him, what does 9 volts means… He only knew the water analogy, but not the real meaning… So your comment did strike a sensitive chord: I am so glad I made you more powerful than I was. This makes me shiver as a teacher:-) ! Good luck and I wish you much enjoyment with the study of this great subject!
You're really really great sir! I'm undergraduate degree physics student and I was struggling to understand the concept "potential" in physics.You just made it clear for me. I want to be great teacher like you who can make things clear for others.Thank you sir🙏
Hello Adane. Wow, I am so proud if I can inspire you in taking a teacher's career. It's one of the most wonderful jobs in the world. Actually, I was inspired during my undergraduate years by a teacher in electrochemistry (A topic at the time I hadn't understand). He was a little rough with us students but he was precise and clear. And when things are clear, the subject can now become interesting! That made me want to be like him (even if I am a little more patient with my students than he was, haha)! With you wanting to become a teacher too, maybe the circle is complete :-)!
@@PhysicsMadeEasy in the same way as your electrochemistry teacher inspired you, I'm really inspired by you and I'm sure you are and will be an inspiration for many. I love the way you explain things and thanks sir for give your time to reply and for your every lecture videos 🙏
Excellent explanations of electric potential and electric potential energy. The concept is simple but for some reason I get them confused. Now the fog has cleared and it makes my understanding of electronics easier.
Thank you for telling me this! This kind of comment is one of the reason why I have created this channel: To help girls and guys like you lift the mist that hinders the understanding of some basic concepts in a topic that you are passionate about. Enjoy the clearer skies!
Great video and explanation! It was absurd for me what Electric "Potential" is, when I was introduced to it You made it so simple :) Thank you very much
Omg, this concept gave me a headache when I tried to listen to the lecture of my professor. On another you explained this in an extremely easy way to understand. Thank you so much sir !!!!!
Hi Sang, I am glad my work helped you unlock this crucial concept for you. Electric Potential It is not a concept that is difficult to grasp, but it can be a pain for students if not explained properly. And this is why I created this channel! Good luck with your studies of Physics!
Im a little confused at 6:30. Is this conventional current? If so is everything reversible for what happens actually. The charge is negative and there is a higher energy on the negative side?
It's surprising that Edouard shows the electric current charge carriers in the external load as positive entities moving from the positive to negative battery terminal. For an expert in solid state chemistry to state this seems odd. Surely the charges 'flowing' in the external connection are electrons, which move from the negative to the positive terminal. The electrons are still moving from a higher to a lower potential having surrendered up that potential energy loss as Joule heating in the external load.
Hi Nathan, Yes, I am using the conventional current. And yes, the concept of conventional current conserves energetical considerations. A question that occurs so often in my videos related to electricity that I made a video to clarify this: "The conventional current?" ruclips.net/video/XzPOGFgsJfE/видео.htmlsi=SfVht1gj5qk2YpfZ
You are correct Trevor, but I prefer to stick with textbook approaches that uses the conventional current, by pedagogical choice, to avoid bringing confusion to the beginner. If I had been discussing of electrochemical reactions, or dug into a more advanced subject, I would have used the real description. There has been such a huge amount of questions and comments about this, that I made a video. Feel free to view it: "The conventional current" ruclips.net/video/XzPOGFgsJfE/видео.htmlsi=SfVht1gj5qk2YpfZ
@@PhysicsMadeEasy Thanks Edouard. I understand your reasoning in adopting this method of explaining what is a very complex physical process. Judging by the overwhelmingly positive comments you receive, your explanations are helping many people struggling with that complexity come to an understanding. All power to you!
I have been scouring youtube as I try to catch up in my physics class. You have got to have some of the best explanations I have seen. I loved your analogy to gravitational potential energy as it really cleared everything up for me. I cannot tell you how sick I am of the goddamn water pressure analogies lol! Thank You!
Hi Diego, the water analogy... me too! I do use it for the lowed grade students that do not understand yet how to manipulate the concepts related to energy, but I do tell them that they will have to fade it out once they get a better understanding. Thank you for your encouragements!
Hi Simbaland, you are warmly welcome. It makes me happy to have helped you understand such a fundamental notion. Now enjoy all the other understandings you can explore from the concept of electric potential. :-)
Hello Roy, that's fantastic: it is for this kind of result that I made this channel (I was in a similar situation as a student). Now, go back to your class notes about electricity, and read them again with this new understanding. Like pieces of puzzle, they should start to make much more sense :-).
I'm 27 and some how managed degree and job without understanding much physics but a part of me always want to understand how everything happening around me, thank you sir.
Hello Steve, That's the spirit! Explaining these concepts in 10 minutes can make the video quite intense... I am really glad you are making the most of them by viewing them multiple times. And if you have questions, there is the comment section :-)
Yes, understanding electric potentials is crucial when dealing with all electrical sciences. That's why I made this video. I am glad you appreciated it :-).
This helped a lot. I've been searching for a good explanation of electric potential for a lot of time. I couldn't wrap my head around the idea that a bunch of charges of a battery have a potential. But this video explained that it's more about potential energy that these changes are "making" with their field's. And thank you!
Yes, charges do not have a potential. They are positionned at a location with potential, but themselves do not have potential. Because they are positionned at a location with potential, they get potential energy (work was needed to bring them there). I am glad it clarifies things. Still, can you rephrase your last sentences so I can check that you really got it?
Thank you! When I started teaching, I realised students had no clue about what is an electrical potential. They were just getting buy by applying the rules. I actually asked an electrician, friend of mine, that I employed to do some of the electricity in my house, he actually didn't know exactly what it was, just how to handle it in his job. I said to myself, I need to do something about that!!! Hence this video. I am glad it was so helpful to you :-)
Hi Ahnaf You are correct: in a circuit, it is the electrons which are the charge carriers, and therefore it is negative charges that flow. And it is important to keep that in mind. But for historical reasons, and to be honest, for simplicity and congruence with all electrical definitions, we use a model for electricity where it is positive charges that are flowing (You can imagine positrons flowing…). Of course, it is a model that is physically incorrect, but it is a model that is equivalent to the flow of electrons (+1 Coulomb moving right is equivalent, to -1 Coulomb moving left.). Being equivalent, it provides the same results and is so much easier to use. In the video, I represent the flow of positive charges because I am representing the conventional current: if you hear in class, in text books or elsewhere the term 'conventional current', it means flow of positive charges, when in reality, for electric circuits, it is electrons which are flowing in the opposite direction. Oh btw, "Electricity" or more precisely current is not "the flow of electron", it is the flow of charges... For example, a beam of proton in an accelerator, or a flow of sodium ions between the neurones in your brain, can also be seen as "electricity"...
Hi Sofia, because I use the conventional current. You are far from the first person to comment about this. As a response, I made a video on the conventional current: ruclips.net/video/XzPOGFgsJfE/видео.html
Hey im confused. at 6:18 you say "Charges are stacked together" But i don't understand how. Charge is a property not an object so how can they be stacked together?
Hi. You are correct. Of course, when I mention a 'charge', I mean a particle that carries a charge. I discuss this in a video somewhere: If I had to say charge carrier or particle with a charge each time, the lectures/videos would become quickly indigestible! In the video, I use the conventional current model. In reality (electron flow model), it is the electrons that are stacked at the negative pole by a chemical reaction occurring in the battery (an oxidation that releases energy provided to pack the electrons together). That's how electrons are packed: the chemical energy is transformed into electrical potential energy until the energy provided by the reaction is not enough to stack more (which in the end, defines the voltage of the cell).
@@PhysicsMadeEasywhat i understood is that : the source has negative charged stacked on one side (not considering conventional current) due to electrochemical reactions. Stacking these charges uses energy as negative charges repel each other. When a conductor is connected , nature tries to minimise potential , thus the charge flows to the area of low potential where charges arent stacked.thus this electric potential energy generates the movement ( kind of how PE leads to KE). When enough charge flows there , then there is equilibrium since there are electric charges on both the terminals . Since there is equilibrium now , brining a charge from infinity to the terminal would take the same amount of work , thus the same potential . This leads to zero potential difference over time , and thus the battery stops working when there is not enough energy to stack the electrons and maintain a potential difference. I know the model we study including flow of electrons is not precisely the model used at high level physics , but i think it explains correctly the basics. Pls let me know if im wrong
thank you sir!!!🙏 before this video I'm confused about electric potential and voltage but after this videos it become very easy to understanding this for me
Subscribed sir, I'm seeing this is what the students needed to understand about all of this basic concepts through a wonderful explanation and visualization. Thank you Sir for explaining
Thank you Rinnie. Maybe you know this today, but the fact that you want to study or not should not be determined by other people (I had horrendous professors in high school, but it didn't deter me, it actually made me want to be a teacher later in life, which I am now). If you want to study, go for it, pick good books, enroll in solid online courses, and do so at your pace!
This was really well explained! Thank you! I just have one question regarding electric charges flow (@ 7:05) . Aren't the electrons that flows? Thus not the positive, but the negative charges that flows from (-) to (+) in the case of the battery?
Absolutely. In electrical circuits, we use conventional currents where it is the positive charges that are moving around. Energetically, it is equivalent, and easier to handle when doing calculations. Besides, in many official definitions (for example electric fields, field lines etc...), the test charge is always positive, so it makes things easier to relate.
Thanks Aryan, as long as I help students around the world, I am fine without the million views :-)! Being a RUclips Star would put too much time pressure on me haha, I have my real life students to take care of!
Thank you Disha. Yes, I've been through that too when I was a student. That's why it was important for me to post such a video. I am thrilled that I was able to help. Thanks for hearts. Here are some from France ❤❤❤ :-)
Sir, It was my luck to see and watch your video. Many on RUclips make their efforts to explain how gravitational potential energy and electrical potential energy related by some similarities in defining them. All are good but your explanation is outstanding, excellent. Thank you sir 🙏🙏🙏. I will watch other videos and share it. Thanks sir 🙏🙏🙏
Thank you Mareena, I am glad you find my videos useful: It's the whole goal of my channel to help students that are struggling with these concepts. I choose the topics just by observing my own students... Please feel free to share with anyone that can benefit from these!
Hello Sakari. It's a convention. V(AB) indicates change of voltage when going from A to B, where A is the reference potential (the "zero" if you will). V(AB) is actually VB calculated in reference to VA, that is why it is VB - VA. I hope this helps!
Hi Shahare, I am glad you enjoyed this video. I 🧡 thermodynamics, I think it is really a fundamental pillar of physics. And, it is true I don't have many of these on my channel. It's on the list !

Thank you so much for your kind words. I am glad you enjoyed my approach!
if emf is not a force , why the name so?
It's a convention @@naveensingh5787
It was superb.......I had understoood in a such a way.....THAT MY MIND BEFORE WATCHING THE VIDEO...AND AFTER WATCHING THE. VIDEO....😉
Nah man, we all owe you quite some appreciation for your wonderfully explained video using simple analogy. Hats off to you!
Thank you Ahnaf, I am glad you enjoyed this video!
wow, there were two whole eurika moments when something clicked in my head watching this video. and i am 34 years old. thank you. subbed!
Inspiring "haha" moments with my vids, I love that! Thanks for letting me know, it truly encourages me! ❤❤❤
Such an illustrative and simple way to explain something that seems so complex. Even a physics inept like me was enlightened, thank you sir keep up the great content
Thank you, NoSide. I am glad that my work enlightened your understanding. Let it be a door for you to understand more about electrical tech!
I'm glad I discovered your channel. Thank you for taking the time making these for us.
Hello sir ..i am from India .. studying in 10th grade ... I was not able to understand this concept.. .. but this video helped me ... Thank you so much
You are welcome Atul, I am glad my work helped you.
In Grade 9-10, that is when a student starts to be confronted with this concept. If you continue in science, you will see the notion of potential showing up all the time, so it is essential that you understand it well as soon as possible!
Lucid, direct and clear explanations.
Something to note about a common point of confusion is the difference in nomenclature between the concept of energy and work.
This really helped to make that difference stridently clear and really helped to tie it all together
Thank you Dr. Reny🙏
Thank you Mello Cello for these encouragements! I am glad this video was helpful to you!
Thank You Sir, I had been struggling to grasp this concept for a very long time until I came across this video. Thank you very much. 👍
You are warmly welcome. I am glad my work pulled you out of your struggle :-)
That was smart of you to move to an outdoor setting in this video. It gives a sense that you are more human and keeps the listener involved.😊
Hey John, thanks for noticing :-).
Indeed, it gives a little air, to have these little interludes outside where what was seen is briefly summarized: It makes it more pleasant to watch, and in the end, might stick better in the viewers head. I should do this on more videos!
Great visuals! I had never had this easy time in grasping concepts like this one. Keep up the good work sir!
Thank you Jitendra, your words are very encouraging!
I love you man. Thanks a lot, I wonder why our teachers don't explain this concept like you did in classrooms.
I wonder too... My channel is kind of a reaction to the hard time I had in High School. Still they exist: some lucky students are exposed to such teachers (I had some at Uni that took the time to make me bloom, and they became my inspiration)
I'm loving this series. I needed it so badly
I'm in uni and I've been dealing with these notions for years and it feels like I've never really understood them until now. Thank you so much what a great teacher!
Thank you Marie for your very kind words. If my video brought you a new understanding, then dig out your old school and Uni notes related to electrical sciences, especially those you are still fuzzy about, and rework them with that new understanding...Haha moments await you :-)!
Best video i have watched so far about PE. No video made me understand about it, except this video. Thank you very much sir
Hi Paradox. You are welcome, and thank you for the encouragement! I am glad it helped you unlock the understanding of such an important concept in physics!
Amazing explanation and even more amazing visuals. Superb content. Please continue doing more physics videos! It is a massive help to students like me who self study!
Hello Malek, Thank you very much for your kind (and motivating) words. I will try to find some time for that. And I am super glad my work does help so many students around the world. Good luck with your studies!
Dear Dr. Reny, I really appreciate the quality of and effort behind this video ranging from the animations and intuitive explanations to even the changes in location while explaining said concept, as a student this really helped me grasp a vital concept i was unable to before. I thank you very much for making this video.
Hello Tango. Thanks you so much for your wonderful comment. I am glad my approach helped you understand and assimilate such an important concept. Review your previous class notes (those you took before you understood what an electric potential was), and reconstruct them based on your new understanding.
Be ready to get crowded with 'ahah' moments :-)
@@PhysicsMadeEasy i sure will sir!
The most underrated channel of all time.
Thank you! It's probably because I do not like having ads on my videos, thus, they are not promoted by youtube (Although I heard RUclips is going to force it soon)! Don't hesitate to share the channel link or the videos, so that others can enjoy some Physics fun!
With the gravitational potential, the potential will not be released unless there is an available path for the object to get closer to the ground. In other words, a ball stuck in a well won't spontaneously jump up out of the well to then go and roll off a nearby cliff. Why then will charged particles with an electric potential effortlessly travel in every possible direction through a labyrinth of wires to reach a lower potential (even if the path they take involves travelling in the exact opposite direction of the lower potential)?
Do they just have way more energy than soccer ball in a well? Or what?
Hi Fletcher...
A positive charge will never flow naturally to a higher potential, even if by doing so it would then have the opportunity to reach a potential which is lower. What you described here is called a potential barrier...
Charges will not cross that barrier naturally unless their carrier is provided with a surplus of kinetic energy (like the ball in the well, will not naturally jump out unless pushed out of the well to overcome the potential barrier which is the depth the well).
There is one exception though: the tunnel effect (Quantum mechanics), but that only works at a microscopic scale.
Maybe you have an example that triggered your question?
Or maybe you forgot that conducting cables are equipotentials (the electric potential is the same in the cable, whatever its shape...)?
I'm trying to understand how electricity is formed on the human body, and this video helped me a lot. Thank you so much!
Our whole nervous system and brain works because of local potential differences, that causes charged particles (ions and molecules) to move around and do what they are supposed to do. For example, me scripting and shooting this video, was a firework of electrical sparkles in my brain.
I am glad that you experienced also such firework when viewing the video ;-) .
@@PhysicsMadeEasy I have a quick question.
Let’s take a circuit, that has a resister. Let’s also say the voltage of a battery is 9V. Now all the voltage drop is across the resistor. Yet, the circuit keeps moving after the voltage drop.I don’t understand how exactly that is possible. If you have a battery of 9V and and voltage drop across a resistor of 9V, why does electrons keep moving. Would it have already lost all the potential?.
A second question as well. When electrons go through a resistor, it loses kinetic energy by collisions with other atoms. Then how can the Amperage entering the resistor equal the amperage out of the resistor?.
@@MarkSmith-vo1vn Hi Mark, your confusion comes from the fact that you consider that the energy provided from the battery is transferred to the Kinetic Energy of the electrons… The energy provided goes to the Potential energy of the charges they carry. Through the resistor, it is the charges that lose energy.
Just to give you a perspective. Mass of an electron: around 10^-30Kg, typical drift speed of an electron: around 10^-5 m/s. KE = 0.5mv^2, that’s around 10^-40J. Potential energy (= qV) of the charge carried by an electron, placed at a potential of 9V that’s around 10^-18J. That’s 10 billion trillion times larger.
If you want, you can see the electrons continuing to move because they are just pushing each other like dominos… They are kind of “drifting”, hence the term ‘drift speed’. Ina circuit, the energy transfers relates to the PE of the charges.
@@PhysicsMadeEasy So all the kinetic energy gets turned into thermal energy. And The electron repulsion gives the potential Therefore the electrons have the same speed. So, then my next question is why doesn't electric potential decrease as you get closer to the protons. Is it because it is all relative to the electrons pushing it. I am kind of confused whether the potential of repulsion or the potential to go to the protons. Or does it balance out. The closer you get to the cathode the further you get from the anode.
The way you explained everything was just incredible. I am so glad I found your channel. Thank you!💙
Hello Ada,
Wow, these are encouraging words! thank you,
I hope you enjoy the rest of your voyage on Physics Made Easy airlines!
you are so good that I can cry. I'm have been watching videos for months about voltage. You are the best
Thank you for these very encouraging words! I am glad the videos helped you in understanding electric potential and voltage.
hands down the best explanation on the internet.
Thanks Mitch :-)!
Amazing!
I‘ve tried to understand the voltage so many times through other videos, but you are the best I fully understand the voltage. Thank you so much.
I am really grateful for your feedback! You just expressed the reason why I have created this channel ! ❤
Awesome you are the best communicator I have met and I am a professional civil engineer, but had difficulty understanding voltage. Thank you very much.
Hi there, thank you for your feedback.
I am glad I could clarify this for you. By following rules, you can always manage without really understanding the physical concept behind voltage (tbh, I went through a large fraction of my uni studies that way).
Maybe you can go back into passed projects where this concept was used, and see what you could have done better. I certainly did when I finally got it!
Omg can't thank you enough!!!! You've no idea how helpful this is.❤
Hello Fariha, I am so glad my video helped you with your studies. Thank you for the feedback, it encourages me. ❤
It Is unbelievable to see a professor like you
I wasn't able to understand this as in India as many comments say don't have that good professors/teachers
But Today I finally Understood the Concept Each Bit :D
Another surprising thing is you are actually clearing doubts of Each guy in comment section as well !
Subbed and Liked The Video Sir
Thank you Niko! your comments show that my work on RUclips is reaching the goals I set for myself :-)
@@PhysicsMadeEasy welcome sir
sir i got confused on this topic since 2 moths and i tried to understand the concept but i can't understand , finally today you have clear my all dought , thanks a lot
Hi Shambhu, I love reading these kind of comments because these reflect the exact objective I set for making these videos. Thanks for letting me know! It makes my day :-)
Out of every video that I saw, this is the best explanation so far for the concept. Keep the great work sir.
Thank you so much for your kind feedback! ❤
Interesting videos!!!!! Very helpful, you are now my favorite RUclipsr!!!!
Wow! thank you for these encouraging words! :-)
Hi sir, I am currently doing my Master in Electrochemistry and after watching this video I realized that until today I did not know what actually electric potential was. I am eternally grateful to you, keep going!
Hi Medina, thank you for your comment.
I studied some electrochemistry at Uni, a hard topic but one I enjoyed because of it being so borderline between Chemistry and Physics. Then, when I worked as a researcher for a large company, I used my free research time to create an electrochemical lab because I was interested in looking at the impact of chemically induced films (oxides or organic) for the corrosion inhibition on various metals (in pipes for example). I was quite successful at it.
The strange thing is that me too, I did not have a good understanding of what an electric potential exactly is. I had made my own idea, close enough for what I was doing, but when I reviewed the school physics programs before starting my teaching career, I realised I hadn’t really understood it. I wish I had, because it would have made me much more powerful in my research: I probably would have won a Nobel prize lol!
I also realised that not many people do understand electric potentials. A friend of mine is an experienced electrician, working in that field for years. He worked the electricity of my house ( I paid him for that), One day, I asked him, what does 9 volts means… He only knew the water analogy, but not the real meaning…
So your comment did strike a sensitive chord: I am so glad I made you more powerful than I was. This makes me shiver as a teacher:-) !
Good luck and I wish you much enjoyment with the study of this great subject!
Finaalllyyy understood this…..ive spent literally 3-4 days just on this topic…..feeling so good now!
Thanks Kushrov for letting me know! I am super happy that my video had this effect on you!
You're really really great sir!
I'm undergraduate degree physics student and I was struggling to understand the concept "potential" in physics.You just made it clear for me.
I want to be great teacher like you who can make things clear for others.Thank you sir🙏
Hello Adane. Wow, I am so proud if I can inspire you in taking a teacher's career. It's one of the most wonderful jobs in the world. Actually, I was inspired during my undergraduate years by a teacher in electrochemistry (A topic at the time I hadn't understand). He was a little rough with us students but he was precise and clear. And when things are clear, the subject can now become interesting! That made me want to be like him (even if I am a little more patient with my students than he was, haha)!
With you wanting to become a teacher too, maybe the circle is complete :-)!
@@PhysicsMadeEasy in the same way as your electrochemistry teacher inspired you, I'm really inspired by you and I'm sure you are and will be an inspiration for many.
I love the way you explain things and thanks sir for give your time to reply and for your every lecture videos 🙏

Thank you Nana!
Excellent, Fantabulous!!! No one would've ever explained in this manner. Thank You!
Hello Sriram, thank you for the compliment :-). I am glad you enjoyed it!
Excellent explanations of electric potential and electric potential energy. The concept is simple but for some reason I get them confused. Now the fog has cleared and it makes my understanding of electronics easier.
Thank you for telling me this!
This kind of comment is one of the reason why I have created this channel: To help girls and guys like you lift the mist that hinders the understanding of some basic concepts in a topic that you are passionate about.

@@PhysicsMadeEasy thats nice
Great video and explanation!
It was absurd for me what Electric "Potential" is, when I was introduced to it
You made it so simple :) Thank you very much
It was the same when I was a kid. I had to fix that :-)!
this is the best explanation i've ever had
Thank you Sarah!
Omg, this concept gave me a headache when I tried to listen to the lecture of my professor. On another you explained this in an extremely easy way to understand. Thank you so much sir !!!!!
Hi Sang, I am glad my work helped you unlock this crucial concept for you. Electric Potential It is not a concept that is difficult to grasp, but it can be a pain for students if not explained properly. And this is why I created this channel!
Good luck with your studies of Physics!
Im a little confused at 6:30. Is this conventional current? If so is everything reversible for what happens actually. The charge is negative and there is a higher energy on the negative side?
It's surprising that Edouard shows the electric current charge carriers in the external load as positive entities moving from the positive to negative battery terminal. For an expert in solid state chemistry to state this seems odd. Surely the charges 'flowing' in the external connection are electrons, which move from the negative to the positive terminal. The electrons are still moving from a higher to a lower potential having surrendered up that potential energy loss as Joule heating in the external load.
Hi Nathan,
Yes, I am using the conventional current.
And yes, the concept of conventional current conserves energetical considerations.
A question that occurs so often in my videos related to electricity that I made a video to clarify this:
"The conventional current?"
ruclips.net/video/XzPOGFgsJfE/видео.htmlsi=SfVht1gj5qk2YpfZ
You are correct Trevor, but I prefer to stick with textbook approaches that uses the conventional current, by pedagogical choice, to avoid bringing confusion to the beginner.
If I had been discussing of electrochemical reactions, or dug into a more advanced subject, I would have used the real description.
There has been such a huge amount of questions and comments about this, that I made a video. Feel free to view it:

I loved your analogy to gravitational potential energy as it really cleared everything up for me. I cannot tell you how sick I am of the goddamn water pressure analogies lol! Thank You!
Hi Diego, the water analogy... me too!
I do use it for the lowed grade students that do not understand yet how to manipulate the concepts related to energy, but I do tell them that they will have to fade it out once they get a better understanding.
Thank you for your encouragements!
i ve never understund the electric potontiel until i watched this incredible video thank u soooooo much
Hi Simbaland, you are warmly welcome. It makes me happy to have helped you understand such a fundamental notion. Now enjoy all the other understandings you can explore from the concept of electric potential. :-)
Thank you so much sir!! I couldn't understand this topic since 9th grade and now I'm in 12th, you really made this topic easy😄😄
Hello Roy, that's fantastic: it is for this kind of result that I made this channel (I was in a similar situation as a student). Now, go back to your class notes about electricity, and read them again with this new understanding. Like pieces of puzzle, they should start to make much more sense :-).
I'm 27 and some how managed degree and job without understanding much physics but a part of me always want to understand how everything happening around me, thank you sir.

I really enjoy your videaos; need to watch them several times to grasp it.
Hello Steve,
That's the spirit! Explaining these concepts in 10 minutes can make the video quite intense... I am really glad you are making the most of them by viewing them multiple times.
And if you have questions, there is the comment section :-)
Thank you so much for taking the confusion out of these important concepts. 🙏
Yes, understanding electric potentials is crucial when dealing with all electrical sciences. That's why I made this video. I am glad you appreciated it :-).
This helped a lot. I've been searching for a good explanation of electric potential for a lot of time. I couldn't wrap my head around the idea that a bunch of charges of a battery have a potential. But this video explained that it's more about potential energy that these changes are "making" with their field's.
And thank you!
Yes, charges do not have a potential. They are positionned at a location with potential, but themselves do not have potential. Because they are positionned at a location with potential, they get potential energy (work was needed to bring them there).
I am glad it clarifies things. Still, can you rephrase your last sentences so I can check that you really got it?
Potential energy is a property of the charge, and potential is the property of the point at which the charge is placed, right?
@@learningisfun889 You got it! 😊
Best best the best and great.i bow my head on your explanation.its taken me 15 years and you solved in 5 minutes
Thank you! When I started teaching, I realised students had no clue about what is an electrical potential. They were just getting buy by applying the rules. I actually asked an electrician, friend of mine, that I employed to do some of the electricity in my house, he actually didn't know exactly what it was, just how to handle it in his job.
I said to myself, I need to do something about that!!! Hence this video.
I am glad it was so helpful to you :-)
Thank you so much for making this video, it made it very understandable and easy to grasp the concept.
Hello Suzana,
Glad I could be of help :-)
I got my answer here, awesome video. I have been searching for it in many videos and finally I reached here.
God bless you Sir✨
Thank you for letting me know: I am glad my work helped you!
Hello Sir, I have a question. Why is there a flow of positive ions at 7:07 when electricity is actually the movement of electrons?
Hi Ahnaf
You are correct: in a circuit, it is the electrons which are the charge carriers, and therefore it is negative charges that flow. And it is important to keep that in mind.
But for historical reasons, and to be honest, for simplicity and congruence with all electrical definitions, we use a model for electricity where it is positive charges that are flowing (You can imagine positrons flowing…). Of course, it is a model that is physically incorrect, but it is a model that is equivalent to the flow of electrons (+1 Coulomb moving right is equivalent, to -1 Coulomb moving left.). Being equivalent, it provides the same results and is so much easier to use.
In the video, I represent the flow of positive charges because I am representing the conventional current: if you hear in class, in text books or elsewhere the term 'conventional current', it means flow of positive charges, when in reality, for electric circuits, it is electrons which are flowing in the opposite direction.
Oh btw, "Electricity" or more precisely current is not "the flow of electron", it is the flow of charges... For example, a beam of proton in an accelerator, or a flow of sodium ions between the neurones in your brain, can also be seen as "electricity"...
@@PhysicsMadeEasy much appreciated! 😁
This was so good! Finally my understanding of electricity is clear! Thanks to you ❤ keep making these gems ❤
Cheers Augliyot. I am glad you made the best out of my work! Good luck with your studies!
I have a very major doubt

Hey im confused. at 6:18 you say "Charges are stacked together" But i don't understand how. Charge is a property not an object so how can they be stacked together?
Hi. You are correct. Of course, when I mention a 'charge', I mean a particle that carries a charge. I discuss this in a video somewhere: If I had to say charge carrier or particle with a charge each time, the lectures/videos would become quickly indigestible!
In the video, I use the conventional current model. In reality (electron flow model), it is the electrons that are stacked at the negative pole by a chemical reaction occurring in the battery (an oxidation that releases energy provided to pack the electrons together).
That's how electrons are packed: the chemical energy is transformed into electrical potential energy until the energy provided by the reaction is not enough to stack more (which in the end, defines the voltage of the cell).
@@PhysicsMadeEasywhat i understood is that : the source has negative charged stacked on one side (not considering conventional current) due to electrochemical reactions. Stacking these charges uses energy as negative charges repel each other. When a conductor is connected , nature tries to minimise potential , thus the charge flows to the area of low potential where charges arent stacked.thus this electric potential energy generates the movement ( kind of how PE leads to KE). When enough charge flows there , then there is equilibrium since there are electric charges on both the terminals . Since there is equilibrium now , brining a charge from infinity to the terminal would take the same amount of work , thus the same potential . This leads to zero potential difference over time , and thus the battery stops working when there is not enough energy to stack the electrons and maintain a potential difference. I know the model we study including flow of electrons is not precisely the model used at high level physics , but i think it explains correctly the basics. Pls let me know if im wrong
I learn a lot from your video. Thank you so much.
thank you sir!!!🙏
before this video I'm confused about electric potential and voltage but after this videos it become very easy to understanding this for me

maybe if u were my physics professor i wouldve actually studied. love ur vids!!
Thank you Rinnie.
Maybe you know this today, but the fact that you want to study or not should not be determined by other people (I had horrendous professors in high school, but it didn't deter me, it actually made me want to be a teacher later in life, which I am now).

dude thank u sooo muchh I was literally struggling with it from class 10 you just made it crystal clear 🙇♀🙇♀🙇♀
You are welcome Deep. Glad I could help.
The way you are understand students that was amazing outstanding ☺️
This was really well explained! Thank you! I just have one question regarding electric charges flow (@ 7:05) . Aren't the electrons that flows? Thus not the positive, but the negative charges that flows from (-) to (+) in the case of the battery?
Absolutely. In electrical circuits, we use conventional currents where it is the positive charges that are moving around. Energetically, it is equivalent, and easier to handle when doing calculations. Besides, in many official definitions (for example electric fields, field lines etc...), the test charge is always positive, so it makes things easier to relate.
Incredibly helpful and clear explanation, thanks sir.

Hello Declan, then I reached my objective! Thank you for letting me know. I am glad my work was / is helpful to you.
in 7:29, isn't it VA - VB, and not the other way around?
Hello Sakari. It's a convention.
V(AB) indicates change of voltage when going from A to B, where A is the reference potential (the "zero" if you will).
V(AB) is actually VB calculated in reference to VA, that is why it is VB - VA.
I hope this helps!
