- Why do resistors in series have different voltage? Why does this voltage split in the same ratio as the resistance? Why does the current stay the same?
We answer all these questions by looking at the transients.

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.
Thanks, Memer! Do share it with folks you think will benefit :)
@@Mahesh_Shenoy explain the force produced due to magnetic feild and electromagnetic force.
@@Mahesh_Shenoyi need help bro can u explain us diode capacitor resistor transistor :how do they work how do they behave and every single information i have a exam and i dont have the book
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 ❤
Same
Exactly, I find it honestly so annoying, sure it might be out of the scope of the syllabus, but at the same time it doesn't take a lot of time to give a small but sufficient enough explaination to those who are curious, does it?
That's probably because they don't know :P
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.
As a student in 10th Grade, I can confirm this complex concept is very easy to understand.
Haha, great to hear that
Same here
How much did you score in boards?

huh how???😭😭😭😭😭😭i cant even secure 89%in preboards and I have only 10days left to boards@@GodSahil
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.
One word , just wow, in my whole career no one make me understand like this, hats off to you
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!
electrical engineer here. V=IR does explain it, but of course there are always other ways to explain it. The universe works very different, and largely its analogy that we really understand. Some work better than others of course.
an eternal mystery for me is what happens to current when it goes to the positive terminal
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.
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
FINALLY, honestly, I've been asking myself this question for years now and never got a complete answer. Thanks so much!
Your explanations are great. These are some really helpful videos and they arent even overcomplicated.
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!😊
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
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!
Came here because your own recommendation n now i think it's the best recommendation ever ...thankyou Sir
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.👌👌🙏🏼🙏🏼
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!
Same. My smile too grew bigger and bigger as this video went on!!
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
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!😊
Your explanation was awesome 👌 i had this doubt and now finally got cleared
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
Very long time I have a doubt in this topic ,now my doubt was cleared by this video.thank you so much sir.
I am so glad that it helped!
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 ❣️
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 so much for making us understand this in the most easiest possible way✨
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
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! This video has cleared something very fundamental i was trying to understand about resistors , capacitors and inductors.
i had these confusion for about half of year .
THANKS OF YOURS
You are a hero !. God bless you and all people around you.
Thanks, Artem :)
Bro you just came like a god for my rescue from this problem of same current in the circuit.
I'm dancing right now, mind blowing explanation 😮🔥🔥 thank you very much sir 🙏🙏
Best physics youtuber yet. No doubt!
Hats off to teacher like you 🎉
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!!!!
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
Sir we appreciate your efforts love from uttarakhand ♥️♥️♥️(India)
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)?"🙏
I watched like 20 videos about resistance and non of them answered my questions. Finally, this one did. Thanks a lot! Subscribe :)
That's so great to hear, David. I am glad you liked it
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!
Wow, thanks for those words of appreciation, Suryansh.
A lot of it comes from just spending a lot of time on it. I have been teaching for more than 11 years now.
But a few specific things to think deeper could be to
A) Always ask what if questions. Here, the question would be what if the current was not the same?
B)Try arguing from first principles. Here, the question I had was how exactly is voltage developed across the resistors in the first place? And then can we explain what happens without using words like voltage or current. Purely from the perspective of what happens to electrons.
I guess these two force you to think deeper. Curious to see what others do for deep thinking
Thanks for the question
@@Mahesh_Shenoy I'll surely keep that in mind sir! Inspired by you and a few other teachers, I do aspire to become a teacher in future, and it's a dream to be able to teach as good as you ✨ I'll keep posting my 'what if' in the comments section sir 😁
Also sir, another question, as an instance, the video in which you explained why in a resistive circuit the current remains the same, I searched in a number of books, asked many teachers, but never found the answer... How exactly did u get the answer?
Also, a lil something that I've experienced, sometimes, when I keep thinking about a particular question and I can't find an ans, and while thinking about it I go to the bed.... The very next morning, after a lil bit of brainstorming, I have an ans! Sometimes, I just sit, and imagine stuff, I try to picture electrons and forces in my mind, I try to picture what effect the forces would have, and it brings me closer to the ans
@@suryanshkhatri5570 I think on the resistive circuit, I had already heard about that model.
On the second part, there is actually some research around that area. When you sleep, your brain processes information gathered while you were awake. That's why sleep is super important to learning.
@@Mahesh_Shenoy Thank you sir!
Hi intellect friends
Beautifully explained 👏
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.😊😊😊😊
I wish this was taught in school, everything makes so much more sense now!
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.
Great to hear that
Such a great explanation
Best explanations
Really really thank you sir. Superb explanation sir.
Best 👍🏻 i understand very easily by this video
Thanks sir for the great explanation I really appreciate how you cleared a lot of misconceptions In a simple way .... I wanted to ask you sir about the parallel circuits since the loads on the same branch are connected in series they get the same current but how does the current out of the branches behave and how does the charge accumulation in the branches affect it. Thanks again and hope that you can see my question.
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
Thank you, very helpful
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
Thank u for being my best physics teacher ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Great video, which explains a lot, even though I still have problems understanding how the net force in the wire can be zero.
Thanks, Michael! If it didn’t electrons would accelerate to high speed causing high current causing higher charge deposition causing higher repulsion.
So, it’s a self correcting mechanism
@@Mahesh_Shenoy Then that would imply that once you got the current going, if you took away the battery in this theoretically zero resistance wire, the current would keep flowing?
Loving the discussion!
If we took away the battery, now there is a retarding force on the electrons in that section. Remember, the net force was zero because the batteries force cancelled the accumulated charges' retarding force.
Does that make sense?
I love you man ❤❤ so good explanation
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!
❤️❤️❤️❤️❤️
U. Are great I want to study physics this way
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 am so glad that my questions resonate with so many others as well :D
You are the best sir
May God bless you sir
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
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?
"The charge accumulations provide the voltages." Excellent!
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 TH-cam 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?
Insightful as always, Kou
Such a great vídeo
Thank you
very nice excellent u clear concept
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) .
Ah sir thnx i now understand. Its good to know
You are doing god's work
I am thankfully i found your Khan academy videos
Wow, thank you!
Wooow thank you sir❤
GREAT VIDEO
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?
Sketchbook!
Best video in terms of concept. So Sir are you able to provide a video like that to explain why voltage in parrallel is the same?
Thanks sir
Thank you to clear all my doubts sir!! But please tell me why the force is going to be smaller in 7:02
does charge accumulation also occur with alternating current?!!
thanks much for these videos
you deserve much
subscribe :) ❤
Very nice video
its very underated vid
Awesome 👊
Sir please make a video on resisters in parallel circuits. And also how the resistance of parallel circuits are calculated
❤❤❤awesoooome content,👍🏻👍🏻👌🏻👌🏻wow.excellent
Thank you!!! Very useful video. Could you explain how current is induced?
Yes, soon!
Tysmmmmmm❤
Wow, great explanation. I understand the theoretical part of eecs but often have a hard time making sense of it intuitively/logically like this. Do you refer to papers or books for this deep circuit analysis like this? All i find are theoretical answers proposed through the use of equations.
Mostly online research. I try to look at the equations and distill the intuition out. And then share it
Ooo thanks alot 😊
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?
Love you hogaya sir ❤️
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 never comment but this video blew my mind.
Great video! Can you make same video but about parallel circuits? Please?
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.
Thanks and oops
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🙏🙏
Sir can u like create a video on Magnetizing intensity (H) , magnetisation intensity (I) , permeability,chi ,hysterisis curve relations
Adding it to the list!
ایول پسررر👏👏
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!
When there are no negative charges, the area will become positively charged, because all the negative charges are accumulated on the negative side of the resistor and the electrons passing the resistor are very less
Sir,at 2:23 you said that here is high current but in this circuit the value of current in everywhere should remain constant.
