I am in Turkey, lesson's language is English but our instructor speaks Turkish always. Although he speaks Turkish, your explaination is more clear than our instructor's for me. Thanks much.
at 9.00 in video,why did u short circuit the voltage source and open circuit the current source to find the output impedance ? i mean what basically is output impedance and input impedance mean ?is it thevenin voltage across the output and input terminals or something else ?
he utilized z parameters ..... these parameters are use to calculate input and out-put impedance... if you search on google you can check what are the conditions to observe while following these parameters....
It's actually a procedure made to ease our work, voltage sources are shorted and current sources are opened. For proper explanation check out Thevenin's theorem (Thevenin voltage and Thevenin resistance)

Thanks Neso Academy! Godbless you!
i really appreciate your work, Neso academy
tysm
sir your videos r really more useful sir pls upload more videos soon sir...... these videos r simply easy to understand
sir, i previous discussions you said for stability Re >> Rb/(beta+1).but why you have taken Rb >= 10(beta+1)re.
Sir your vedios r really helpful. Plsss upload more n more vedios sir. Ur explanation s really easy to understand. Tq sir tq so much
For Output impedance why we short circuit voltage source and open circuit load resistance
to caculate Zo ....................................xd
Thevenin's theorem.
sir how we can prove for re model of common emitter .sir why forward resistance is always replaced by re irrespective of configuration

But fixed-bias dont have Re right?
how do we comply the terms there?
Why is Rs not considered during calculation for Zi? Thanks in advance
I think same also....have you got a
Answer???
can we solve the circuit by h parameter model?
Sir, why should we open circuit R-Load for finding z0..
kindly reply..
Raghunandan Madhav
if we don't do that then a voltage will drop across that ..and we will nt able to find complete drop across z
u r awsm....thank u very much...
Why you always do source voltage short ckt. and load=infinite during the calculation of output impedance
IT ALWAYS EAT UP MY HEAD 😫😫😫

Sir is their any website wer we can get your notes?
same question
tq sir
Why Rs is connected there? Can anyone answer my question
It is serial connected to source, we can replace it to upper line but nothing changes. Same things
I didn't understand define Zi
😊😊
❤
srry,there i meant to write thevenin impedance
