Fr. After a while concepts become so simples

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 :-)

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.

Thank you Ashutosh, your comment shows that I am achieving my goal: Making Physics Easy (without making it incorrect! ;-) )

Agree

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!

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 :-)

Hello Shiva, thank you for your kind words. I am glad my work helped!

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 so much for your kind words. I am glad you enjoyed my approach!

if emf is not a force , why the name so?

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!

Hi Chandler Bing :-) ! I am glad my work helps you make sense of things!

Thank you Ahnaf, I am glad you enjoyed this video!

Thank you Mello Cello for these encouragements! I am glad this video was helpful to you!

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.

Thank you for these very encouraging words! I am glad the videos helped you in understanding electric potential and voltage.

Hello Ada, Wow, these are encouraging words! thank you, I hope you enjoy the rest of your voyage on Physics Made Easy airlines!

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 :-)

Cheers Augliyot. I am glad you made the best out of my work! Good luck with your studies!

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!

Hello Sriram, thank you for the compliment :-). I am glad you enjoyed it!

Hello Fariha, I am so glad my video helped you with your studies. Thank you for the feedback, it encourages me. ❤

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!

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!

Thank you so much for your kind feedback! ❤

Thank you Jitendra, your words are very encouraging!

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)

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!

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!

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 :-).

Hello Joshua, thank you very much for letting me know. This type of comment hits the right spot about why I created this channel!

Hi Angu, thank you for letting me know. I am really glad I unlocked some concepts for you. So yes, good idea to jump back to your old notes and exercises, and see how these make sense now!

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!

Thank you Nana!

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 Niko! your comments show that my work on KZfaq is reaching the goals I set for myself :-)

@@PhysicsMadeEasy welcome sir

Hello Suzana, Glad I could be of help :-)

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 :-)!

Thanks Kushrov for letting me know! I am super happy that my video had this effect on you!

Thank you Simon, I am glad I was of help!

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! 😊

It was the same when I was a kid. I had to fix that :-)!

Wow! thank you for these encouraging words! :-)

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.

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!

Thank you Black Pearl. I am happy the video enlightened you :-)

Thank you for your kind words :-)

Thanks Mitch :-)!

Thank you very much for your kind words. I am glad you enjoyed my work :-)

Thank you Sarah!

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 so much for your encouraging comment!

You are welcome Deep. Glad I could help.

Super, goal attained! Thank you for your feedback ❤

Hi, Thank you for your kind words. I am glad my video helped you understand such an important concept. Now you can enjoy exploring deeper, there is a whole world of electrical knowledge that awaits. :-)

You are most welcome Herman!

Thank you for your kind words!

Thank you very much for your kind feedback. I am glad my work helped!

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!

Thank you for these kind words :-)!

Thank you, I am glad I could transform super brains into hyper brains ;-)!

Thank you for your kind words! I am happy my videos help you in understanding fundamental concepts in physics.

Thank you very much Abdullah for your encouraging words :-)!

Thank you for letting me know: I am glad my work helped you!

You are most welcome Arun !

@@PhysicsMadeEasy 🤩😊👍🏻

Hey YMPS, I would be proud if you got an improved mark at your exams thanks to my work. Good luck!

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 KZfaq 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!

Thank you for your very kind words. I am glad that my work helped you out. With all my students, I very much insist on a good understanding of the basics: Bright students can manage without sometimes, by just using the rules, and mimicking standard exercises, but sooner or later they become limited in their ability to understand more advanced concepts and can lose interest in the topic, although they would have become amazing physicists otherwise...

Hey Shrihari. Electric Potential is not easy to initially grasp for students (it wasn't for me when I was one!). That's why I made this video. I am super glad I cleared a little bit of your path in Physics!

I am glad I could help Parinit!

Hello Cala, you are welcome and thank you for the kind words!

Hello Aymen, in chemistry the concept of electric potential is really central in order to understand the interaction between species. All the interactions in chemistry are related to the charges these species carry, and how these charges are distributed in space. So I am really glad my video clarified a few things for you. See how this applies in your field of expertise!

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 Rajesh! More than mundane, critical!

@@PhysicsMadeEasy Yes ! Absolutely foundational concepts.

Thank you Anand! I hope it helps with your studies. All my wishes of success!

You are very much welcome Kaleb!

Inspiring "haha" moments with my vids, I love that! Thanks for letting me know, it truly encourages me! ❤❤❤

You are welcome ar4850, I am glad you find my approach to explaining concepts like this one useful.

Thank you for the encouragement Gabriel. I am glad my video helped :-)
