Why resistors in series have different voltage (but same current)? 

how is this not the first thing taught in electronics courses.

It's a shame these amazing videos have only a fraction of the views that other videos that cover syllabus specific topics have. You teach not just restricted to the syllabus but in the spirit of passing knowledge, and for that you have my utmost respect.

The 10th grade , teachers are only teaching the thing which are in the book , not deeper than that and if we ask them questions they ignore us. Thanks a lot for posting these videos which solves our doubts ❤

You are asking all of the questions that I am wracking my brain with. Most answers don't adequately explain it either - they use V = IR as a basis and you're just supposed to accept things as a given. Thank you for having the courage to address these questions, and the rare talent to be able to break them down logically and clearly. Please keep it coming!

One word , just wow, in my whole career no one make me understand like this, hats off to you

As a student in 10th Grade, I can confirm this complex concept is very easy to understand.

Very long time I have a doubt in this topic ,now my doubt was cleared by this video.thank you so much sir.

My smile grew bigger and bigger as this video went on. You are an absolutely amazing teacher and your passion for passing on knowledge and understanding on a deeper level to people shows! As an apprentice trying to understand what's really happening instead of just plugging in formulas you have cleared up so many of my lingering questions that my teachers were failing to answer. You are amazing!

Interesting. So essentially, right after the circuit is closed, there is a very very short moment of transient that dictate what's happening in the circuit. 1. Right after the circuit is closed, all electrons in the circuit experience the same amount of force which is due to the battery. However, different sections of the circuit would experience different currents: all wire sections experience (relatively) high amounts of current while the resistors experience relatively low amounts. 2. Because the resistors impedes electron movement, they tend to get accumulated at the start and end of the resistors. Negative charges accumulate at the start while positive charges accumulate at the end. The amount of accumulation depends on the resistance of the resistor. This is also the reason why there is different voltages on resistors of different resistances. 3. The accumulation of charge eventually affects the movement of electrons in the wire sections of the circuit. They eventually a. decrease the force experienced by the electrons on the wire and b. increase the force experienced by the electrons on the resistors. 4. This cycle continues until we reach the steady state, where the current is the same everywhere. It is important to note that the accumulation of charges does not disappear even after the currents in all sections of the circuit equalizes.

This video explained things so well. When you first hear about the fact that current is constant it feels so counter intuitive but you explained it so well.

this topic was eating my brain away . it wouldn't be difficult if i accepted the knowledge of V=IR as told by my teacers , but the problem arrised when i question why in series and parallel resistors things haapen as they . you cleared my concept of series . can i pls get a parallel concept too. your video was the best

Learning about Electricity for the first time, I was extremely confused. Everyone on youtube just explained the formulae, until i found this channel. Amazing!! Now I could actually imagine what's going on.👌👌🙏🏼🙏🏼

FINALLY, honestly, I've been asking myself this question for years now and never got a complete answer. Thanks so much!

Yah doubt Maira bahut Pahle Se tha teacher se puchne ke bad bhi samajh Nahin Aaya but now I can understand thank you so.... much sir

I am being honest here, I knew this before watching this video, one day I was just wondering about this and somehow intuitively it clicked to me. Today I got the confirmation.

Sir, you teach for a reason And I'm all here for it I knew the formula for potential divider beforehand But because of this video sir, I can become one with the formula. I FEEL the formula I UNDERSTAND the formula I observe as this knowledge flows through my veins All thanks to you sir

Omg bro your video is like magic The second you said that charges accumulate I understood the whole point Thanks for the great video and clearing my doubts

Sir, I've always wondered, how did you get to know this stuff? How did you get to learn things in this way? I rarely find a teacher as good as you at explaining stuff, you explain each and every thing, just in the way I wish to understand... I want to understand science the way you do... What's the secret sir? I'm a first year BTech student, from India... I shall eagerly wait for your reply sir!

I'm graduated in EEE. I remember I was doing my first course of circuit, my head were bursting with questions, one of those was this question, but no faculty could answer my question. Hopefully, finally I get the question.

I had to figure this out all by myself, because no one is ever talking about this fundamental stuff in the typical electronics courses, they might not even know or care about it. But this stuff is crucial to get a _real_ understanding of why things are the way they are usually described. I figured that we have a highly dynamic situation here on a physical level and that there must be some setup and some equilibrium state, and mostly we only care about the equilibrium state (that what you call the steady state). But it is the way this equilibrium state comes about, when and how and for what reasons the initial dynamic situation settles, that makes all the difference. Thanks for confirming.

You are a hero !. God bless you and all people around you.

Im 19 and about to start my electrical engineering studies and had so many questions about the little details of how things work including this one and can't thank you enough for your videos, you're big, bro. Wish you a happy life

You have really quenched my thirst of curiousity.

Thanku so much for cleaning this thing. I was tired asking this doubt to my teachers but the answer "hota hai toh hota hai" 😢. Finnally understood the concept. Thanks ❣️

Came here because your own recommendation n now i think it's the best recommendation ever ...thankyou Sir

Please continue making videos like this. It greatly helps us. Thank you for giving time and effort to make this video. More blessings to you!

Best ever explanation I have ever found sir out of the world 🎉🎉❤

i had these confusion for about half of year . THANKS OF YOURS

U. Are great I want to study physics this way

Thank you sooooo much for this beautiful explanation. I owe you for this. and yes you have one more well deserved subscriber now. 😊😊😊

Thank u for being my best physics teacher ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

an eternal mystery for me is what happens to current when it goes to the positive terminal

I always have a doubt resistor resists current but while calculating effective resistance across serious circuit of different resistance the current remains constant I wonder how that possible!!!!! and you cleared that in awesome way😊. I salute to the work you done sir!!👏👏 Atlast I found the masterpiece answer for it!!!!

Amazing explanation! I had this doubt but couldn't find the solution anywhere. This channel is truly underrated. But one question I still have. How is the voltage across all the resistors, when added, turn out be the voltage of the battery?

Such a great explanation

I'm dancing right now, mind blowing explanation 😮🔥🔥 thank you very much sir 🙏🙏

I had no idea that electrons can bunch up. I always thought that when one atom loses a free electron, that it immediately draws in another and as such electrons could only shuffle along one at a time. I understood amperage by understanding that this represents the speed at which they move along but i could never understand how the potential difference between two points on a resistor could have changed... I thought since they all move along in an orderly fashion the voltage was set by how many electron were in the negative port of the battery vs the positive and as such wouldn't/ couldn't change. Now that i understand the chaos of them bunching up and in a way turning each resistor into its own battery cell with its own little positive and negative port it makes so so so so so so so much more sense. I love the chaos, it makes more sense than order sometimes. Thank you so so much!!!!

Bro you just came like a god for my rescue from this problem of same current in the circuit.

Jesus Christ!, Your explanations are pure gem how can you have such low number of likes 😮 you for sure are the only one on yt who made me understand it, keep it up!😊

Sir we appreciate your efforts love from uttarakhand ♥️♥️♥️(India)

"The charge accumulations provide the voltages." Excellent!

Thank You so so much sir, I have been beating myself up because I just couldn't understand why in series circuit current is same, then when we study voltmeter they say that oh we use high resistance to lower the current flow but wait current remains same...... Many more examples of this and I just... Thanks for this

Beautifully explained 👏

Your explanations are great. These are some really helpful videos and they arent even overcomplicated.

Thank u so much for making us understand this in the most easiest possible way✨

Amaaazing!!! I had a lot of confusion while reading resistors in series and this has actually been a great explanation. Now I have completely understood the topic and definitely learned something new! Keep up this great work!😊

That's really fascinating. One thing I'm somewhat frustrated about in my EE journey is that often, I just accept so many conventions or explanations on why this or that thing works without knowing why those happen. This video addresses one such explanation. Thank you. Also, I'm not sure if you've already done it but I really hope you'll also do a video for parallel. The idea of resistors in parallel having same voltages across it just does not and have not made sense to me at all. I just know it does but I don't know why it does it.

May God bless you sir

Amazing! This video has cleared something very fundamental i was trying to understand about resistors , capacitors and inductors.

I wish this was taught in school, everything makes so much more sense now!

Your explanation was awesome 👌 i had this doubt and now finally got cleared

I watched like 20 videos about resistance and non of them answered my questions. Finally, this one did. Thanks a lot! Subscribe :)

This Is Very Helpful Brother Thanks

Sir, I'm a student of class X from Bharat🇮🇳🚩, I'm here to understand the concept behind series connection of resistors.. While watching your video, I just got a doubt that why are positive charges accumulated on the other side of resistors. Please help me in clearing my doubt!

Gr8 video, i am a tenth grade student and this question was revolving inside my mind i asked my teacher then she says something like" bla gla aba daba jaba 😂😂" and i am like what, what you saying it was going all over my head 😅, then came you my saviour, my satisfactor, loved your video

Hats off to teacher like you 🎉

Outstanding video! Thanks for this!

A simple yet important key concept that gets missed in textbook and by teachers as well, great video! At 2:51 you mistakenly said maximum current instead of max resistance.

Great video, which explains a lot, even though I still have problems understanding how the net force in the wire can be zero.

You are doing god's work I am thankfully i found your Khan academy videos

Really good video, it would be nice if you would have shown what the voltage was in volts at the end, that would complete the whole picture for me

Amazing video! This could be your niche in the RU-vid educational platform. Anyways, how does the thickness and length of a resistor influence its resistance? The beauty of the universe never ceases to amaze me. Is there any chance that all of this occurs in nature and not just across our artificial wires?

Sir please make a video on resisters in parallel circuits. And also how the resistance of parallel circuits are calculated

Brother what an explanation hatsofff to you keep it up brother keeep going so that we can learn as much as we can from you

Sir can u like create a video on Magnetizing intensity (H) , magnetisation intensity (I) , permeability,chi ,hysterisis curve relations

Best physics youtuber yet. No doubt!

I had been searching the reason for 2 days😢.but I couldn't find, even asking many teachers.but you explained me it clearly sir. Sir,in addition to that I have a doubt for which I can't find the answer still, which is,"why the battery gets heated when we put a magnet with it".sir I hope you will reply for this as soon as possible.eagerly waiting for your reply sir.😊😊😊😊

Thank you sir for your nice explanation on this very confusing topic. I will be highly obliged if you clarify one of my doubt regarding this topic. My question is why the accumulation of the charges still stay in the ends of the resistor when the number of electrons going inside the resistor is equal to the number of electrons going out of the resistor after the transient stage( I mean when the current outside the resistor is equal to the current inside the resistor) .

Does accumulation of charges concept violate Conservation of Charge Principle? Is it correct to assume that there is charge accumulation happening at both the end of Resistors? I think we must consider the effective Resistance offered by the Resistors and the ratio in which it is split. Consider an Open Circuit or Circuit with Infinite Resistance. Can we say Charges accumulate both the ends of the Open Circuit?

Thank you for making the video. I see that the distribution of charges creates a force, but in this scenario 1st resistor has less force compared to the 2nd one then why the current stays the same? Sorry you have already answered that. Thank you for making the video

Cool explanation

your videos are amazing and are very easy to understand. i am really grateful that i came to know about this amazing channel.❤❤ can you please make a video on "Why resistors in parallel have different current(but same voltage)?"🙏

watching this kind of videos in last year of the graduation to understand the basics!!!!

GREAT VIDEO

Please make a video on "why voltage is same in a parallel circuit?"

its very underated vid

Sir, you said the current changes, but sir according to physics current should not be changed it remains the same, only the voltage change 👀

Excellent sir

Really really thank you sir. Superb explanation sir.

very nice excellent u clear concept

Best explanations

You are the best sir

Great video, very intuitive explanation. I break my head about the question - if i connect DC motor with series resistor to a voltage supply what is going to happen. in 1 direction you can determine the resistor in series by set the current you want through the motor and the voltage. but how its work in the other direction? if i have given voltage source with given series resistor and i want to connect a dc motor to this circuit - what will happened in transient time that make it work?

thank you so much sir... Can you please do a video on "What happens to the current flow in a parallel circuit where one of the parallel wire gets fused or the bulb in one of that parallel connection gets fused" like let us imagine there is a parallel connection where 3 bulbs are connected in parallel and 1 ampere of current flows through each bulb, total current would be 3 amp... but when one of the bulb gets fused, will the 1. rest two bulbs receive a current of 1.5 amp 2. or if not where will the current go away?

I so thankfull to you, because you are doing these fantastisc videoes on physichs, rogth now on the world of electricity. I think I learn much more about your topics, when you -much more than others - are doing videoes and tell about, what you are doing in them. You got a very great talent, and I really hope, you will come to a time, where you for sure are at the right pkace, and are doing your succes into science. It could be into education or so, but I rarely hope to see you make a breakthrouh in science, because I sense your love for these topics. Whatever!, your science videos are surely in the top or at least among the very vest science videoes. In top, becouse you are showing spetacular interesting fenomens, and you show it and speak about it, so everybody get a better understanding, you show what exiting for you and you tell about it in a way, where you hitchhike me for 20-25 min and thereafter leave me as a clever and a more courious man, who have more love for the humanity, I - and everybody I know - is a part of. You videoes are as good as, it isn't possible to tell everything, I wanted to tell. But i love your channal and I hope all yours best will come to you. Better sooner, than kater! ❤️❤️❤️❤️❤️

Hi sir👋👋. You explained very well about resistors in series. But I can't visualize how resistors in parallel work.... We connect resistors of different resistance, then the charges accumulated in the ends of resistors will be different, then how we say the voltage stays same across all resistors??? Please make a shorts or video about this sir🙏🙏

Great video! Can you make same video but about parallel circuits? Please?

Sir,at 2:23 you said that here is high current but in this circuit the value of current in everywhere should remain constant.

Awesome video! Quick question. What software do you use as blackboard in the video? Also what advice would you give to a new physics teacher?

Thank you!!! Very useful video. Could you explain how current is induced?

Best 👍🏻 i understand very easily by this video

4:34 Hi, I don't understand this part, where did the positively charged protons _come_ from?? Because until I watched this video, I thought that electricity only deals with _electrons_ , not protons . I understand that generally speaking, like in chemistry or something, a decrease in electrons = an increase in protons. But when it comes to electricity, I thought we were dealing with electrons _only_ ?? Where and how did the positive charges come from?? Thank you

❤❤❤awesoooome content,👍🏻👍🏻👌🏻👌🏻wow.excellent

Its really stunning ! So at the very first instance current would not b same evrywhere,a few moments later it d reach equilibrium state...Am I right sir?.

Sir, how current are different in parallel connection and same potential difference.

I want chemistry video on carbon compounds like how soap is made

Ok this is incredible 👏👏👏 But you said that forces only exist inside the resistor after the whole process. So the electrons should speed ip inside of resistor and therefore not slow down. Then how can a resistor RESIST the flow of current?

Ah sir thnx i now understand. Its good to know

finally the Millennium problem solved ,satisfied

Thank you to clear all my doubts sir!! But please tell me why the force is going to be smaller in 7:02
