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