3 An n p n transistor is used in common emitter configuration as an amplifier with 1k2 load resistance Signal voltage of 10mV is applied across the base emitter This produces a 3m4 change in the collector current and 15u4 change in the base current of the amplifier The input resistance in kilo ohm is
