This is the first good thing which 'you tube' recommended me

90%of people just came to watch his teaching style😉

Great to see a veteran in field clearing fundamental doubts of students thereby encouraging us to invest out time in this beautiful subject.

The students who studied in his class are sooo lucky

This is one of most haunted questions in Physics. Verma Sir is a legend of our country.

I had book of HC Verma in year 2001 , that time I was in 11th class. My teacher, VK Handoo told to go through HC Verma... Though I managed to buy but never managed to get that level of potential in myself to read and understand it.... It was very very good book that time. One of the finest book that time. I never imagined that I will see its author one day.... Especially in you tube.... I'm surprised that after around two decades after I purchased I will be able to see HC verma sir, giving lectures on his books.... Glad to see this... Our generation is very unlucky that we don't had KZfaq in those days....

My god!!never thought verma sir would have KZfaq channel why is KZfaq recommending me this channel after 4 years

This genius made Physics understandable to the human being!

His simplicity in delivering lectures in an example which we young generation should look upto....man with knowledge + man with value = a real man..thank you sir.

Physics:I'm inevitable Hc Verma:I'm HC VERMA

BIG FAN SIR AWESOME METHOD OF TEACHING, BOOKS THAT YOU'VE WRITTEN HAS HELPED A WHOLE GENERATION OF STUDENTS. MAY GOD BLESS YOU SIR, STAY HEALTHY, SAFE. SALUTE TO THIS GENIUS

If I remember correctly, the Ohm's law states that current (I) is proportional to the potential/voltage and not the other way around. So I °< V. °< is used by me for proportionality symbol. And R is an entity independent of these two (current and potential) and is a proportionality constant and this will not vary. When I say it will not vary, I am talking about static resistor used. We can definitely use variable resistor but at a given point of time, it will be constant. Plus the negligible resistance from the conductor material which again should be constant and depends on the material/metal used. And when it comes to potential being zero, it will never be zero. There will be some negligible amount of potential difference which is very very close to zero. And hence, there will be current. 2 A is very huge but it was just an example used for mathematical validation of V=IR. In reality, that zero is indeterminate as you guys rightly said because that value is very close to zero. Let's say 1 mV or even less and a negligible resistance of < 1 ohm from conductor assuming 0 for resistance like sir said. The value will have more zeros after the decimal point and in reality something dividing by something will give a value no matter how small both values are and hence that value is current which is not zero. Hope this is useful 🙏

I think this question is the same as asking how an object in frictionless space can travel with a constant velocity despite not changing its potential energy. It does so, because objects in motion must remain in motion until acted upon by an outside force. In this case the electrons in the wire experience a change in potential energy across the resistor that provides them with the kinetic energy to complete the circuit. The motion of the electron through the "frictionless" wire is not due to a potential difference in the wire, but to conserving kinetic energy in the absence of an outside force.

HC Verma,,, : True Legend

You are the my inspiring Sir. You are the gem of India. One of the greatest teachers of Physics of the century. Very kind hearted. Yes, MIT has Walter Lewin sir. IIT has H C Verma sir. May God bless you all the time and be happy sir. Lots of love from Assam, India Thanks a lot for the video

A very classic and practical example of why 0/0 is undefined. 🤗

For people who didnt understand , heres the logic , you have 2 tanks at the same level connected with a pipe so no water flows because they have the same level of water , as soon as you connect a 3 rd tank to the 1 st 2 tanks with less water, the rate of flow of water from the 2 tanks which have 0 difference in water height start flowing and their heights decrease at the same rate filling the third tank . So verma sir s logic holds good

I never thought that HC verma sir has a youtube channel.. Thanks youtube for suggesting this😁😁

If anyone is feeling weird about 0 being on both sides of the equation, it's not 0. There is a little amount of resistance offered by the wire and that section of wire has a potential difference twice the amount of that resistance. Keep this in mind and watch the video again and you will get it. Edit: twice because current is assumed to be 2 amperes

Good observation Subhankar. In job (10years after I completed 8th std) while designing a circuit, I realised that my teacher forgot the assumptions and it never stuck me. For every concept, all assumptions must be included so that students understand concepts perfectly.

why is this video in my recommendation im a commerce student 😂

Really he is " HC VERMA " ??. I never imagined he has a KZfaq channel .... but why subscription is very less ???

12 years after studying his book. This is the first time I am seeing "The HC Verma"

He should have 50 million subscribers as more than this no of students have studied sirs book

Legend HC Verma has his own channel omg daamnnn😂❤❤

I love the ease with which you explain fundamentals. Thanks :)

This is very interesting. Thank you for sharing and for the wonderful explanation!

I remember this doubt getting raised in my mind in my school days but it was cleared when I got to know that every wire has some resistance and this is just a representation

Actually the current drawn from a voltage source depends on the external resistance ( here) or overall resistances present in a ckt. Current - effect , overall voltage diffence - cause...and it's value depends on resistance...so it never see the potential difference somewhere locally zero or not....this is the concept he is trying to convey us. Ohm's also satisfied in the region where potential difference is zero.. Thanks sir...great explanation...

I am blessed to see you first time Sir through this video. I hope you will keep us blessed with some important videos that you think is appropriate and must for your students.

Thank you sir and the student who asked this question. It indeed was a great question. I never thought about this untilll now. Sir, huge thanks for the beautiful explanation.

So much respect for him.

An example of a real life application would be great! I studied Electrical Engineering in the US, so I understand circuit analysis

Thats my confusion of all time but now its cleared , awesome knowledge sir

आपका पढ़ाने का तरीका काफी दिलचस्प है। ❤❤❤

1:44 Sir is really enjoying the question.

2 minutes of silence for those who are relatives of him and are in their board year

The answer to this was clear to me when i took R of CA as negligibly small instead of being zero.(since, conducting wires do have a small resistance). i in CA has to be equal to that in AB assuming it's a steady current. So the i in CA is some finite value. Then, using V=iR for CA, you see that since R is really small, V of CA becomes negligibly small. So there is a potential difference between CA it's just negligibly small(and because the resistance is also really small, a good current can still pass) (Pls correct any mistake)

Sir mera bhi bilkul same doubt aur Maine Kafi time iske liye search kiya but muge koi solution nahi mila but at last KZfaq recommended me your video and my doubt is cleared .you are a great teacher sir .thanku so much.

You are the world best author and teacher in physics 🙏

Sir I am really glad to find this channel on KZfaq ... Thank full to you master ..

Sir....you are such a great man with a great heart!!!!!

I feel soo lucky that H.C Verma sir is teaching me through youtube :) I came here because I don't understand the Electricity chapter, so thought to teach from H.C.Verma sir

Everyone's dream to be taught by him...

Your work is devoted to the service of physics 🙏🙏

"This Is How Me Make The Figure Of Resistance Although Resistance Never Looks Like This"-HC Verma Sir..... Had Me Rolling Sir Ji😂

HC VERMA CONCEPTS OF PHYSICS VOL 1 AND VOL 2 *BEST* BOOK EVER. YOU ARE MY SAVIOUR SIR🙏 NO OTHER BOOK WHICH I HAVE READ EXPLAINED THE CONCEPTS AS CLEARLY AS YOU DID SIR🙏🙏🙏🙏🙏🙏🙏🙏 THANK YOU.

How simply sir explained, is unbeatable

I'm aspiring physics students. Very professional discussion. Proud of you

Sir you are really a legend in the field of Physics....the way you taught this concept in such a simplistic manner was amazing. Thank you sir!!

God of physics 🤚🙏🙏🙏 Hats off to u sir , please teach whole 11th and 12th physics for jee we will be delighted and our concepts would become strongest ... Please sir 🙏🙏🙏

What an excellent way of explaining!

Really awesome teaching sir. And it's really the most typical question that you explained in very easy way. Respect from the depth of my heart ❤️

You are also a conceptual man sir you are legend

Best video i found today in KZfaq. ❤

This proves that in present time best education doesn't matter but advertisement matters. that's why other platforms have more than 5 million subscribers and HC Verma have only 500k .🙏

0 divided by 0 can be anything. So 2 Amp is just fine :)

Legends are not proved by there subscribers They are alone enough

Thank you I was so confused about this in short circuits this clears up a lot

Hc Verma sir on KZfaq? Ooohhh a miracle for the universe and a dream come true for me lol

After HC Verma Sir who wants RD Sharma sir on KZfaq hit like 👇

thanks for solving the difficulties

Didn't expect this level of clarification... KZfaq did recommend something good

I have no words to describe my emotions after seeing this video 1st time in my life youtube recommend me such a nice video which made my day worthy Thanks to KZfaq India 🙏

Yes , the connecting wires are considered to be thick enough to be considered as resistanceless. Thanks Sir.

To be honest, I was searching for a physics question answer related to dimensions but KZfaq suggested me ........😅

Sometimes I understand and sometimes I don't but I love watching your videos❤️

Very great concept sir ❤️ with a logical conclusion. 🙏

Theoretically, but surely in a practical example it is impossible to ever have 0 ohms resistance, as even in a wire or in any component there will be at least a negligible amount of resistance thus requiring at least a negligible amount of potential difference for any current to flow. PS: I love your lecture style and you explain the concept really well!

Sir, when will the translated to English version of the new book will be available?

It's KZfaq's one of the best recommendations ever 😀

I am blessed with this small logical videos Even though I am a Product Design Engineer these high school physics is really a good fundamental booster in applied engineering

when backbenchers studies physics lmao

Sir, i think the question he meant was that. How current can flow in that wire from A to C in spite of the potential difference between a and c is zero.

I had also this doubt but after watching this video there is no doubt 🙏🏼🙏

i am so stupid why haven't i asked myself this question yet! i learned something new today. thank you sir as always. you are a legend!

One of the best teachers I came across in my life. I simply love his books and recommend them to all my niece and nephews. I was hoping for this one, he would also explain, how zero by zero resulted in say 2 amps. By explaining that voltage difference approaches zero and resistance approaches zero but they are not absolute zero. The ratio turns out to be the current value we see when measured by a device - which happens to be same as current across resistance. For example 1 to power 365 is 1. But 1.01 to power 365 is 37.7. So zero to power zero is not defined but this is not exactly zero by zero.

HC Verma sir is saying only about Vc and Va or Vc and Vb.Not about Va and Vb .There is a potential drop across Va and Vb due to the battery. So current flows from higher potential to lower potential. Now I think his explanation is complete.

No ad on any video. He's great

Oh god.... Hc verma has a KZfaq channel! Subscribers should be in millions

Sir you are god of books And u are teacher of teacher May god bless you And publish more books like thiz h c Verma is really the Bible of physics ^o^

So proud of our very own 'The Explainer' - à la Feynman. Never knew the legendary Verma Saab had a channel. Thanks for making Indians enjoy and fall in love with Physics. God bless you Sir !

current without potential difference, H C Verma, you beauty😍

I wish , Every Physics teacher should be like This Legend 🙏❤️😊

Let's understand Physics. We appreciate your support 🙂😊

Sir 11class ke motion (3) chapter ka questions 11&12 .ka answer kaise calculate hoga.plz give me ans.book concepts of physics. By H.C Verma.

Ur teaching style is fabulous sir 🙂🙂🙂

I will be blessed to learn with him

Sir could you please make a video on Norton Theorem & Thevenin Theorem.

Super question My explanation is...... If u measure Voltage with reference of ground. Both points A and C have some potential becoze internal resistance zero. Va-Vc=0, but where as in practical we get some very minor voltage drop bcoz no material shows 100% conductivity. At the same time point B we found some dropping of voltage .

Its outstanding that he is still working on stuff

Yr bhut Acha lgta h Sir Ka video dekh ke ... Bss sir Ka pddane Ka style dekhne ke liye subscribe kr rakha h🙏

as we know there is no force required to move a body in an uniform motion provided there is no friction.. similarly if there is no resistance(friction) the charge keeps on moving without potential difference(force) and hence there is current.. as in case of superconductivity

I am a big fan of Verma sir

Very nice sir g.... Uh are doing very good work for any one who wants to learn

You make things look so easy and interesting sir; doubt cleared. Thank You

This went over my head actually

Yes current can flow only if there is a potential difference... But it is not necessary to have a potential difference between any two points, instead there should be an overall potential difference in the loop in which current flows.. Example: if you short circuit a cell, that is connecting positive terminal directly with negative terminal with an ideal conductor, then there will be a current flow even after having zero potential difference across the wire. It is due to the fact that the cell creates a potential difference in the circuit. We are lucky for getting blessings from you in the form of classes sir.. 🙏🏽

First time I have seen tha HC verma sir.

You r genius sir your book HC Verma is so conceptual I could not solve it when I take hc Verma in 12 th class
