Question #76094
State, with reasons, whether the following statements are True or False
Amplifier with common emitter mode offers maximum current gain
Amplifier with common emitter mode offers maximum current gain
Expert's answer
Common emitter amplifier current gain is given by (∆I_c)/(∆I_B ) .
∆I_c = change in collector current
∆I_B = change in base current
As change in base current have medium effect on collector current because collector resistance is high. So, current gain becomes medium not higher or maximum.
Answer: Statement is ‘False’.
