In a transistor connected in a common emitter mode it has, `R_(c)=4kOmega, R_(i)=1kOmega, I_(c)=1mA and I_(b)= 20 muA.` Find the voltage gain.

Text Solution

Verified by Experts

Voltage gain `A_(V)=beta((R_(0))/(R_(1)))=(i_(c)/(I_(b)))((R_(0))/(R_(1)))=((1 xx 10^(3))/(20 xx 10^(-6)))((4)/(1))=200`
