A transistor is usedin common emitter mode in an amplifier circuit. It is found that when a signal of 20 mV (millivolt) is added to base-emitter voltage the basecurrent changes by 20 muA (micro ampere) nd collector current changes by 1.5 mA (milli ampere). Determine the current gain b, Input resistance Ri, transcondutance and voltage gain. Give load resistance R_l = 6kW (kilo ohm).
