Hi All
May I know the reason why sometimes we need to short circuit the output in order to find the curent gain or voltage gain of a circuit? Why do we need a short circuit current gain?
Usually we wish to know the voltage gain or current gain of a circuit? Why? Just a stupid question, is it true that when we are interesting in current gain for a circuit, that implies voltage gain is almost negligible?
Kindly enligthen
rgds and thanks jason
