In a common emitter transistor amplifier...

In a common emitter transistor amplifier the audio signal voltage across the collector is `3 V`. The resistance of collector is `3 kOmega`. If current gain is `100` and the base resistance is `2 kOmega`, the voltage and power gain of the amlifier is :

A

15 and 200

B

150 and 15000

C

20 and 2000

D

200 and 1000

Text Solution

Verified by Experts

The correct Answer is:
B
`A_r=beta R_c/R_B`
`A_v=100 times 3/2=150`
Power gain =`beta A_v`
`=100 times 150=15000`
