Sir please keep your channel videos backed up.I heard that Neso Academy channel has been hacked.It's better to keep videos backed up.If we do so none of our videos will be lost.We can re upload again.
direction of current source in large signal model should be taken opposite to what is taken as it is npn transistor, current should be acc to arrow in transistor from p to n
In NPN transistor, the collector current flows from collector to emitter side. At the emitter node, the summation of base current and collector current is equal to emitter current. So, here it is satisfying the KCL. If you consider the direction of current source opposite then it won't happen.
Should I model bjt as voltage controlled device or as a current controlled device ,because if we look Ic=IS.exp(vbe/vt) We can see collector current is a strong function of vbe , so can we say that bjt is voltage controlled but if we this it's voltage control the equation become very complex to solve , also looking in data sheet how will we find reverse saturation current IS
@@PavithranD22 Saturation current is for forward-biased diode current, and reverse saturation current is the small reverse-biased current, also known as leakage current.

nice lecture
Owesome👌👌
Very good 👌
Can u explain large signal model of PNP transistor in active mode
Thank u ❤❤
@ 4:18 Vt is threshold voltage

Great 😍😍😍😍
Nice😄👍😎
Brother what did you study ? Where are u working ?
Please check the about section of the channel. You will get it.😀
Note that : Is is saturation current, Not reverse saturation current.
Bro can you explain what's the difference?
@@PavithranD22 Saturation current is for forward-biased diode current, and reverse saturation current is the small reverse-biased current, also known as leakage current.
@@ayush-indokay bro .. shouldn't Is be the reverse saturation current
Osm
sir where is digital electronics playlist. Please reply
Flip flop etc
It is yet to be covered on the channel.
@@ALLABOUTELECTRONICS I think it was there just two months ago.
Explain a bit slower...not able to pick it up.
It's not all students problem

your usage of "the" is wrong, just telling.
