First slide

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


 Here, RO=800Ω,Ri=192Ω , current gain, β=0.96

 Voltage gain = Current gain × Resistance gain 


 Power gain =[ Current gain ]×[ Voltage gain ]
