I am doing an assignment which has asked me to find the effect of varying \$V_{EB}\$ on paramaters such as voltage gain , current gain and input resistance for the following circuit :
I attempted this question by hooking up a voltage source like this :
But when i run the circuit , it shows "Failed to find DC Operating Point for AC analysis" .
Why it's showing such an error and how do i get to plot \$V_{EB}\$ along the x-axis ?
