A npn transistor is connected in common emitter configuration in a given amplifier. A load resistance of is connected in the collector circuit and the voltage drop across it is 0.8 V. If the current amplification factor is 0.96 and the input resistance of the circuit is , the voltage gain and the power gain of the amplifier will respectively be:
View answer and explanation
Correct option: A
4 3.84
Option A (4 3.84) is correct because the voltage gain and power gain are calculated using the given current amplification factor and resistances.
