sir plz do not change your way of teaching .and avoid what others say about you i like way you teach

Agar hum jiska last orbit mya 6 and 7 electron hai uske sath silicon ka dope kare to kya problem hogi..? N type semiconductor hogi ya nehi..? Sir plz answer..

Great Sir 👍👍👍

Thank s a lot sir 👌👌👌👍👍👍👍👍👍👍

[@anil.82]

Thanku sir ... we all have lost a gem of physics. RIP sir 😥

[@pratikthakkar3240]

Sir why would the high energy electron of phosphorus sit in the valence band though at room temperature they have sufficient energy to jump to the conduction band??or is it because by sharing of four electron their 18 octet is completed??would they compensate their high energy for octet completion??

[@uchidamadarasenju7175]

+Pradeep Kshetrapal sir u r the best.. I would definitely recommend people for your lectures.. they are simply superb... this is coming from a tibetian. a Buddhist who want people to understand the way a universe work through your vision

[@uchidamadarasenju7175]

***** I would like to buy your complete notes. But I don't know how

sr i am from nepal but have totally understood thank u so so much sr you are great teacher

[@noobtextwritergamer]

I like tune sir. What's its name

[@aartijha2078]

Sir u said that no of free electrons is greater than no of holes but holes aren't formed in valence band

[@souravsingh1433]

😀😀😀😀 nice lecture

[@himanshuraj1476]

than you sir

[@rekhasohan2112]

Sir in the absence of electric field do holes constitute current

[@user-eb8gr8lf8h]

No dear because of electrons will eject by attaining more energy and then left from original position at that location create a hole... Hole is depend on when electron will eject..... Electron will expel when source is available...

[@hdeep2243]

when will class 12 syllabus get completed

[@prayasjain9780]

sir does your lecture cover the entire portion which is needed for CBSE boards or something aditional is to be studied

excellent video sir.....

[@tripledotsx2382]

Sir n type me bhi toh electron & holes equal honge ,ek electron free ho rha h toh hole create hoga na sir, plzz reply sir

[@Manjusharma-rm4kc]

Hole create nhi hoga bcoz pentavalent impurity ki vajah se electron aaya h...and kyunki hum atom m atom add kar rahe hain that's why its neutral

[@NehaKumari-rb3xp]

Sir u r jst awesome 😍

[@neerajvishwakarma3914]

Nice lecture

which camera u r using to record this lecture.

[@gehlotharish1922]

[@silimisra4225]

Sir why don't we just use hexavalent or bivalent impurity

[@user-eb8gr8lf8h]

You can do but semiconductor devices of tetravalent elements have less energy gap.....

Nice sir

[@SaurabhSingh-jm6xi]

Sir if the no of free electrons increases then no of holes decreases then how conductivity increases

I am not able to understand the concept of energy level of n type

[@saleembasha9666]

Sir why do you take soooo long to complete a small concept in a chapter? Seriously one can complete this intrinsic and extrinsic semiconductors topic in maximum 30 minutes but you took an enormous 1 and half hour to complete the concept? Why can't you keep your lectures short and crisp. You repeat a small point again and again so many times that the student is bored to death. Please try to keep your upcoming lectures short and to the point. No offence sir but this is just my opinion.

[@sidratulmuntaha3024]

right

[@prabhatarora3037]

hi saleem.. just a suggestion- u can also increase the speed of youtube video in settings

[@aalishanhafeez2691]

Sir wants to make our concept clear. Yeah, he can do this in 30-35 mins like other teachers but he doesn't want to teach us superficially. For entrance examinations you have to study and watch lectures like that. Sir very good job. Keep it up.

[@ikramullah5189]

Saleem Basha what is your problem

[@akashdeepdatta4412]

No Sir. Please don't . Its absolutely perfect the way it is.
