hybrid equivalent model isn't valid for high frequency analysis. hybrid-π model is used in higher frequency analysis..

[@balajisaikumar4145]

Bro ,you just killed it .I'm looking for a vidoe for hybrid π model,this was the best of all among other

[@MaarpuSaadhyulu]

Sir just saw the video for tomorrow exam.I just felt to have a teacher like u to all the subjects that we have.thank u so much and plz dont mind being younger than u i wish u to continously prosper more in life sir

[@anandsahu6767]

This proves every topic is interesting if there is a good teacher..

[@pavansaikumarsamudrapu6357]

Wow you turned the topic I feared the most to the one i understood the most thank you very much sir

[@ShivamPandey-py6fm]

bro i mean wow you just killed it totally in brain and i think i m gonna love that way you are teach us so thank you bro

[@rohith__]

Sir please arrange it according unit wise because we B.tech are seeing this for need of clarity U nailed this video sir

[@supriyarudroju5367]

Thank you sir. you said from the basics it helps to understand the topic easily

[@ushendrasengineeringtutori4259]

Tq🤝🤝.

Best teacher ❤

[@rajasekharreddy5666]

Superb explanation sir...

[@dusasandas5854]

Really very very helpful Doubt sweeping lecture 😊

[@ushendrasengineeringtutori4259]

Tq for considering

[@mrpagluu]

I was much indulged in the class taht... When u missed alpha to write .. I was shouting alpha alpha😂

[@abhishakekorati7323]

From the basics ❤️ thanks anna

Nailed it sir

[@ushendrasengineeringtutori4259]

Thank you 😊

[@muhammedyaseen6701]

Thanks sir❤

[@ushendrasengineeringtutori4259]

Thank you 😊😊

[@grandhalayamitra]

Very Nice Sir you don a good job

[@navaneethdesai]

Sir, why Re =Vt/Ie ? Re=Ve/Ie right sir.... How Ve became equal to Vt(thermal voltage)?

[@ushendrasengineeringtutori4259]

Vt is 26 mV at room temperature. Even that Ve in the discussion is also a voltage and is also practically measured and found to be approximately 26 mV.

[@santosh.travelvlog8492]

End of session gm= ic/26m, units will be megh ohm if i am not wrong

[@ushendrasengineeringtutori4259]

gm is transconductance, reciprocal to resistance. Units will be in mhos.

[@santosh.travelvlog8492]

Ya ya sorry ya mho, but milli amps you said so...

[@navaneethdesai]

Why area of plate changes @10:20?? Distance between them may change due to forward and reverse bias and we can have capacitive effects. But how area of plates(emitter , base and collector) alters sir??

[@navaneethdesai]

Sir can you please answer this?

[@navaneethdesai]

Sir, please can you respond to this

[@ushendrasengineeringtutori4259]

Did I mention that., Okay then let me go through my video and will get back to you. Thank you for coming back to the comment even after one long year. Let me check it and will answer you.

[@Smartandtrendyshopping]

Sir tomorrow my exam sir 😢

[@navaneethdesai]

Why we are considering a separate Virtual Base node B'?? Why can't we take the base B directly? Why no such nodes for Emitter(E') and Collector(C')

[@navaneethdesai]

"why can't we access the centre of the base?" @ 8:15 of this video why we consider like that??

[@ushendrasengineeringtutori4259]

Virtual Base is that point of contact inside the case. How can we touch it. If you want to touch it., Just break the case. This resistance is measurable and detectable only between virtual Base and the other terminals. This is somewhat related to base-width modulation. With the increase in the forward voltage and reverse voltage on either side of the junction. Base region experiences both reverse and forward voltages when the transistor is used in active region. All these factors together contribute towards the concept VIRTUAL BASE.

[@navaneethdesai]

@@ushendrasengineeringtutori4259 Sir, what do you mean by a "case"? Are you talking about the Transistor sir? Sir, even though the Virtual Base(B') is inside the case , it is present 'physically' right... Then why do you say it is physically not accessible?

[@navaneethdesai]

Sir, please can you reply sir

[@ushendrasengineeringtutori4259]

I'm talking about the transistor of course. The upper cap like material is what know as case. Inside it we can find the semiconductor materials. The base, emitter and collector inside the case. And we can't touch it. If you want to, just break the case
