This man is delivering such knowledge for free for which everyone claims huge amount and able to deliver very less....hats off to you sir!

hit like if u agree

[bincyjose]

Sir, please take care of your health, after each class's hard work (continuous talking & writing ) you look very tired, May God shower his blessings so that you can lead children to the wonderful world of Physics, thank you very much sir.

[anusmitasamanta]

this generation is so grateful to have you as mentor. What else we need when physicswallah is there for us.

[hmmu]

Missing alakh sir's lectures, nowadays. 🙁🙁
He is focusing on bigger issues but no probkem sir we love you♥♥♥♥

[choisanismine]

congrats to those ppl who have journeyed with him till the second last lecture of this chap, ... one to

I am a repeater, who was never able to clear the concept of potentiometer in two years of coaching. But then this video by Alakh sir is the best way to clear the concept. Hit like if u agree....

For the last potentiometer problem, I took the cells in parallel by mistake. But I got the same answer as Alakh sir got in series.
Then I found out that the answer will be same for the cases, which I verified by changing the value of any one of the cells and calculated the value of X by parallel and series combination, which gave same answer in both the

Every time I watch sir's video ...I just think how can someone teach with so much enthusiasm, and dedication that too for is literally a legend.

Jockey, Jockey,
Yes papa?
Eating current?
No papa.
Telling lies?
No papa.
Show your Galvanometer
Ha ha ha!

[anujagrawal]

Video ko upload hue 30 sec hi hua h
Aur kisi ne dislike bhi kar diya😤😤😤😡
Matlab inn logo ne 30 sec me hi sir ka 1 hour ka video dekh bhi liya
Pta nhi kaha se aate h aise log

[shoibahmad]

Sir I'm from J&K and most of the times we are under curfew and strikes. Studies were affected badly till you came. Thank you sir✌️
May God fulfills all your wishes ❤️🪐

[rnpsharma]

I feel like a stupid to never find a teacher like u till now.u re a blessing on middle or poor class students.😉

[abhijit]

One best thing that happened with me in lockdown that is, I got to know about this channel and I am very thankful ❤️to sir for providing such awesome content

[akshitdhiman]

6.6 million started this chapter but only 1.6 million were able to end it congratulate yourself if you are one of them

[masad]

India have lots of physics legends. Respect from Pakistan❤️❤️❤️

[AkashSharma-fxcq]

This is one of the best lecture of Potentiometer .. it cleared all my concepts .. thanq vry much sir ❤️💙😍🤩👌

[sumitsoni]

Just wait everybody next year you see 1.2 M to 10M sub

[anandedits]

Jo topic se kuch der pehle dkh k hi darr lg rha tha....thik 1.13.03 hrs k baad wo topic hmse darr rha ....#godonearth

[zjpqxcx]

The clarity of your explanation is amazing... Watching PW videos must be made mandatory for every physics student. 😄

I literally thought there was an Earthquake and Alakh Sir just didn't care because he wanted to teach us.
Sir has created such an Aura that compelled us to think this way.
Love you Alakh Sir, You saved my life by risking your life. :)
