The input and output resistances in a common base amplifier circuits are `400 Omega` and `400 K Omega` respectively. The emitter current is `2mA` and current gain is `0.98`.
Power gain of tranistor is

A

`950`

B

`960`

C

`970`

D

`980`

Text Solution

Verified by Experts

The correct Answer is:
B
Power amplification, `A_(P)= alpha A_(v)`
`=0.98xx980 = 960`.
