In a common emitter transistor amplifier the audio signal voltage across the collector is 3V. 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
-
- 15 and 200
- 150 and 15000
- 20 and 2000
- 200 and 1000
Correct Option: B
Given, current gain β = 100, Rc = 3kΩ,
Rb = 2kΩ
Voltage gain (Av)
| = β = | Rb |
| = 100 |  |  | = 150 | 2 |
Power gain = Av β = 150 (100) = 15000
