Question : 8 of 90

Marks: +1, -0

An NPN transistor is used in common emitter configuration as an amplifier with 1kΩ load resistance. Signal voltage of 10 mV is applied across the base-emitter. This produces a 3 mA change in the collector current and 15µA change in the base current of the amplifier. The input resistance and voltage gain are:
