question_answer
An NPN transistor is used in common emitter configuration as an amplifier with load resistance. Signal voltage of 10 mV is applied across the base-emitter. This produces a 3 mA change in the collector current and change in the base current of the amplifier. The input resistance and voltage gain are: [JEE Main 9-4-2019 Morning]
