35:38 Answer : The junction is very close to emitter since more is the doping less is the width of depletion layer in that part and as the emitter is heavily doped therefore the depletion layer in it is very thin and hence the junction is near it.
It can be thought of like that but it is not. Because that circuit may look like a transistor but it cannot perform the functions of transistors. You can draw yourself circuits in a notebook and analyze the differences between your circuit and transistor.
Bro me neet aspirant hu mene ye lecture concept clarity k liye dekha and its sufficient for u as well , well mene kuch din pehle hi pw ka yakeen batch 4.0 join Kiya h
Yes bro it's done to avoid punch through , if doping is less in the base region then depletion region on the base side will be wider and transistor action is lost . Also we want early voltage to be as high as possible ,so collector capacitance has to be higher which means depletion region on collector side should be wider
43:22 , you cannot have accumulation of charges , if recombination happens in base , charges accumulated, you inject base current so as to keep no. Of holes in base alive and constant

Yep 👍👍
Near the base
its my request on everyone's behalf to categorise all the video in sequential playlist according to chapters
bro just visit neptel and watch all lectures
@@VikashKumar-ug5jx expalin please, I am not able to navigate their site
@@aeonian_harshul just type NEPTEL ,on youtube
and search for topic u probably get all lecture.
No additional benifit bro...same condition in Neptel....
Well let us give a thanks to JIO and RUclips too that we can learn from him anywhere now!
The world's best teacher thanks
Sir aap Jo padhate Hain uski Har ek BAAT se Mera dimaag resonate kar raha Hai mauj kar di sir aapne to
Sir aapko mere hridya ke bhitar Ki Har ek roam roam se bahut bahut dhanyawad🙏🙏🙏🙏bane rahiye sir
I am an engineering student , haven't understand physics that much before 🥺please mr virma make more lectures in english until i learn indian😂❤
Easy to understand explanation sir. Thanks sir
HC VERMA JI GOP GOD OF IIT PHYSICS
Excellent
Sir please make full syllabus video playlist
Welcome sir.
Please make lecture on Lagrangian and Hamiltonian mechanics.
Wow moment the way it is explained
Just gold!!!
Really good lecture. Thank you sir
Sir please make chapter wise playlists
Yes - thanks below. I did figure it out. 35:38
I think the junction should be away from the emitter towards the base. (as it is lightly doped)
Two diodes connected in reverse polarity, does it work as a transistor? Can u please tell sir? The lecture was very nice. Thank you very much Sir.
It can be thought of like that but it is not. Because that circuit may look like a transistor but it cannot perform the functions of transistors.
You can draw yourself circuits in a notebook and analyze the differences between your circuit and transistor.
Junction should be away from the emmiter becouse it is heavily doped and thants why it shorten the deplition layer btw emiter and base junction.
Yah it is sufficient if you simultaneously read with ncert.

Thank you so much
hc verma sir lots of love
Hello sir in Donald neman collector has been shown least doped and base moderately doped..kindly clear it sir

Thank you
Sir Hindi me videos bnaye
attendence lagao 2024 walo
thank you sir
