Current gain in common base configuration is less than 1 because

View answer and explanation

Correct option: C

{I_c} < {I_e}

Option C (

{I_c} < {I_e}

) is correct because the current gain in common base configuration is defined as the ratio of collector current to emitter current, and the collector current is always less than the emitter current.
