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

A

`alpha`

B

`beta/alpha`

C

`betaalpha`

D

`beta`

Text Solution

Verified by Experts

The correct Answer is:
D
`because` P = V x I
`therefore` Power gain = Voltage gain x Current gain
`therefore (P.G.)/(V.G.)` = Current gain = `beta`
