If the Assertion is correct but Reason is incorrect.

Vedclass · Answer

(C) In a common emitter transistor amplifier,the input current is the base current $(I_B)$ and the output current is the collector current $(I_C)$.Since the current gain $\beta = I_C / I_B$ is typically much greater than $1$,it follows that $I_C \gg I_B$,meaning the input current is much less than the output current. Thus,the Assertion is correct.However,a common emitter transistor amplifier is characterized by low input impedance,not high input impedance.Therefore,the Reason is incorrect.

Assertion : In a common emitter transistor amplifier,the input current is much less than the output current.
Reason : The common emitter transistor amplifier has very high input impedance.
