Calculate the voltage gain for the network of Fig. 3.12 if the source has an internal resistance of 100 in series with Vi.Vi=500mV,R= 1K ?
For this problem I had tried a solution but I am not sure whether it is correct or not? Please Help. Below is the solution that i have found
Ii = Vi/Ri = 25mA For this ckt, Ie=Ii=25mA
Since, Ic is approx equal to Ie, Ic=25mA VL=Ic*R=25V Hence, Av=Vl/Vi=50.
Is my solution correct? I am assuming that the internal resistance of source will not have any effect on the circuit. Correct me if I am wrong.
