For a constant collector-emitter voltage of , the collector current of a transistor reached to the value of from , whereas base current changed from to value. If transistor is in active state, small signal current gain (current amplification factor) will be
View answer and explanation
Correct option: B
400
Option B (400) is correct because the small signal current gain is calculated by dividing the change in collector current by the change in base current.
