Does anyone know how to calculate the gain of transistor amplifier circuit?
Thanks in advance

 

one easy way is to take the output voltage and divide it by the input voltage.

 

Thats right...Output voltage/Input voltage = Gain.
It generally is harder to find the output voltage in a transistor circuit though.

 

if u r dealing with ac signals then u can do the ac analysis of the circuit using the hybrid model & then find its input & out put voltages .
Gain=Vo/Vin

 

cheers guys
