Question

In a common-emitter transistor amplifier, the audio signal voltage across the collector is 3 V. The resistance of collector is 3 kΩ . If current gain is 100 and the base resistance is 2 kΩ , the voltage and power gain of the amplifier is, 200 and 1000, 15 and 200, 150 and 15000, 20 and 2000

MARKS App · Accepted Answer

Current gain β = 100 Voltage gain A V = β R c R b = 100 3 2 = 150 Power gain = A V β = 150 100 = 15000
