In a transistor in `CE` configuration, the ratio of power gain to voltage gain is

A

`alpha`

B

`beta//alpha`

C

`beta alpha`

D

`beta`

Text Solution

Verified by Experts

The correct Answer is:
D
For `CE` configuration voltage gain `=betaxxR_(L)//R_(i)`
Power gain `=beta^(2)xxR_(L)//R_(i) implies (Power gai n)/(Vol tag e gai n) =beta`
