A npn transistor is connected in common emitter configuration in a given amplifier. A load resistance of 800Ω is connected in the collector circuit and the voltage drop across it is 0.8V. If the current amplification factor is 0.96 and the input resistance of the circuit is 192Ω,the voltage gain and the power gain of the amplifier will respectively be

Detailed Solution

Here, RO=800Ω,Ri=192Ω , current gain, β=0.96 Voltage gain = Current gain × Resistance gain =0.96×800192=4 Power gain =[ Current gain ]×[ Voltage gain ]=0.96×4=3.84
