A common emitter amplifier has a voltage gain of 50, an input impedance of 100 and an output impedance of 200 . The power gain of the amplifier is
View answer and explanation
Correct option: C
1250
Option C (1250) is correct because the power gain is calculated using the formula: Power gain = (Voltage gain)2 / (Impedance gain).
