Q. What is the voltage gain?

voltage gain is the ratio of output voltage to input voltage. It is represented as Av,vo-voltage

output,Vi-voltage input,Ic-collector current,Ie-emitter current is the impedance

Av = Vo/Vi = Vop-p/Vip-p

Av = Vo/Vi = (Ic*Zac)/(Ie*Zin)

Vo = Ic(Rc||RL) = (-hfb)Ie(Rc||RL)

Vi = Ie{hib+Rb(1+hfb)}

Av = (-hfb)(Rc||Rl)/hib+Rb(1+hfb)
