Sorry but I think that you are wrong that black does not affect our eyes.

you are the most underrated teacher on youtube

सर आपसे पढ़ने के बाद सारे doubt clear हो जाते हैं। इतने अच्छे lectures देने के लिए thanks.

God give you lot of energy, and life . Please keep on doing such videos. If you had come earlier my life would have been different

Through this u I understand much..... !! Thanks 👍SIR

Sir kash mujhe aapka channel pehle se pata hota to main electric feild or electrostatic force and coloumbs law bhi parrh leta overall thank you sir lot of love from pakistan

Sir u r superb. U helped me to understand physics in a very easy way

Thank you very much...I wasn't able to understand this concept earlier but now I got it... Explanation was really helpful was interesting 💕🙏🏻

Best channel but underrated the teacher is very polite and kind hearted

this channel should really have more subs,they teach so much to the point,better than many channels who spend hrs teaching the same topic in such a lenghty manner ....exam ke pehle yeh sab videos bohut hi kaam ata hai

Ak like to Banta hai...you tube Mai bohot Sara video dekhe...par aap Jaise koi nahi samjhaya sir... thank u...

Ultimate explanation ....! Thank you so much sir ...! :-D

u r great teacher in world sir. I learn more things from u. love u sir from our family. thnks again.

Dil se very much THANK YOU Sir, Aapke videos bahut acche hain aur humare exams k liye bahut helpful hain.. Kindly aise hi videos banate rahe, God Bless you.

sir aapka video ka intzaar rahta h hamesha...

Thank you so much for such video..reallly amazing all the videos

that trivalent accepted negative and became negative. and pentavelent which gave became positive was near junction. And trivalent which became negative near p side of junction do not allow further electrons to come and repels it This was very much needed. Kept on thinking and by your that insight of that idea got to know. May be wrong but got some what clarity almost... But still more trying more and more clearer... no need of conventional current direction i guess... But may be useful somewhere donno but it should be changed if nothing...

Thank u for these outstanding videos. It helps a lot. Plss keep going 😊

Sir superb and unbelievable teaching.

Excellent explanation, i was thinking ,ehere would be drift of electrons and holes in unbiased condition, either it will be in whole pn junction diode or in only depletion region where electric field is set, i learnt here that it happens only in depletion region because electric field is set only there

03:22 PN Junction diode allows current on one side and stops on the other side 06:44 Formation of N-type and P-type semiconductors 10:06 Free electrons and holes explained 13:28 Holes carry positive charge and can fill a hole created by an electron shifting. 16:50 Diffusion process and charge influence during movement of free electrons and holes 20:12 P-N junction diode creates a positive and negative potential due to diffusion and electric field 23:34 Explanation of drift current and diffusion current in p-n junction diode. 26:51 Understanding Depletion Region and Barrier Potential

sir background & way of explaination,both are too effective 👍👍

Sir apke padane ka tareeka bahut accha hai thanks sir ji🙏🙏

literally you are god at explaining things.....thank u so much

Sir you are brilliant teacher for phuysics

It was so helpful sirjiiii... Literally without making notes I could solve problems of this chap..... Thanks sir for this... Really it was like movie..... ❤🖤🧡💛💚💜💙💕❤❣💞💝💛💓💗💗💗💖💖💚💜❣❣❣❣

Sir how a hole can move as it just a blank space for atom ..pls clarify will it shift or move ya whole atom consist of of hole containing shell will move

Your explanation way is very smartly sir..😇😇 your voice is very impressive sir..🥰

Thank you so much sir for your great effort

i liked the way u taught in detail each n every thing

Very good channel for easy learning ❤️🔥🔥🔥

Thankyou sir ❤ , your channel is very great everything is explained very deeply , these type teachers are rare and thankyou

Thanku so much sir for the great explaination 🙂

Sir ap jo samjhate he bohot easily samajh atta he Sir 🙏🙏

your voice is amazing sir

Thank you for this explanation 👍👍👍

What is the concept of acceptor ion and donor ion?

For this video thanks a lot sir Nice explaintion

Thankyou sir. Love you.

cool slides and brialliant explanation sir

Thakuu so much sir for ur very very --#exellent explanation ....and we all appreciate ur hard work sir. Thank so much sir😊🤗

Great explanations..!!

Your explanation is just mindblowing thank you very much sir

Sir, Holes dosen't move they just only occur , when there is an vacancy for electron..., Only Electrons move

Very nice sir...

Sir i have doubt,why did holes jumps to n side,if n-side is already fullfilled of electrons and only have free charges which could go to ocvupy holes space

extraordinary class sir

Fantastic and impressive explaination

Namaste Sir🙏, bahut achcha explanation dia aapne😀😀 Thank you Sir🙏🙏

Bhut achha smjhate h

Thanks sir very good for 12 class

Really appreciated

Diffusion bhi kaise hoga sir , kyuki udhar to charges repel kar rahe thai na? Kya drifting ke wajah se repelling force ka magnitude kam ho jayega issliye diffusion bhi chalta rahega ya kuch aur reason hai sir?

wow sir kya gajab padhate h aap❤❤

Sir very helpful

Sir we are missing you so much

THANK YOU SO MUCH😭😭😭😭 I LOVE YOU BRO❤
