Question

Amplifier with common emitter mode offers maximum current gain. True or False

Answer 1

Common emitter amplifier current gain is given by (∆I_c)/(∆I_B ) …………………..(1)
∆I_c = change in collector current
∆I_B = change in base current
As the collector resistance is high , so the base current has medium effect on collector current. So, the current gain is medium not maximum as per equation (1).
So, the statement is false.
