Question
In a common emitter transistor amplifier the audio signal voltage across the collector is 3V. The resistance of collector is 3 k. If current gain is 100 and the base resistance is 2 k, the voltage and power gain of the amplifier is :-
Options
A.
15 and 200
B.
150 and 15000
C.
20 and 2000
D.
200 and 1000
Solution
Power gain = AV = 100 × 150 = 15000
