[tanpreetsingh]

Sir aap toh boring se topic ko bhi acche se samjha dete hu thank you so much

[pwfanwallah]

Wonderful lecture sir.All faculties of mohit tyagi sir are better than every top offline institutes.

[satvikp]

I am currently in IITH (EE IC Design & Technology) dept and am watching this playlist to revise for my "Intro to IC" exam tomorrow😅

[dr.vaishalighodke]

15:29 Sir I think the formula is ni = A(T^3/2)(e^-ΔEg/2RT)

[krishkumariitbhu]

Watching these lectures for the course 'Fundamentals of Electronics & Instrumentation Engineering' @ IIT (BHU) ❤️🔥

[ujjwalkumarsingh]

25:12 Group 15 instead of group 5 and 37:45 Group 13 instead of group 3 I guess... Btw thanks for these amazing lectures

[sakshamjain]

currently in svnit surat ece branch watching these again for my exams tomorrow thank u sir u r great🙇‍♂️

[rajatgautam]

I am neet aspirant and follow your video regularly 🙏😊

[MaxxiGaming]

1:07 14th group i think 25:18 i think 15th group 37:37 i think 13th group✔️✔️✔️ Helpful 🙏🙏

[annonymous]

Literally I won't get this type of clarity in semi before 😁😁😁💪😎

[notsyblus]

The bond between my heart and ABJ sir cant be break, It needs infinite amount of energy.. 😊
Sir you are my inspiration❤❤

[SaatvikPandey-zdbt]

currently in dtu cse, watching this because i have basic electronics endsem in 9 days 😭

[physchopath]

Sirji aap maire liye bhagwaan ho 🙏🙏🙏🙏🙏🙏Aap mast padate ho😇👌👌

[kankanchatterjee]

sir you are god to us . lots of love and respect to you sir

[MohitSingh-jo]

Sir At 1:08 it's 14th group not 4th.

[AvinashKumarTiwari-dbrj]

Currently from IIT DELHI still watching sir lecture for my 2nd semester exam 😊

[ethicalnonhacker]

How many lecture will it take to complete this chapter semiconductor and its devices?? Pls reply Sir

[jee]

Last 2 questions were very interesting and concept builder

[masoombari]

Thanks sir I have strated following you sir for jee 2021 sir can I crack
