An n-p-n transistor having a.c. current ...

An n-p-n transistor having a.c. current gain of `50` to be used to make to make an amplifier of power gain of `300`. What will be the voltage gain of the amplifier?

A

8.5

B

6

C

4

D

Text Solution

Verified by Experts

The correct Answer is:
B
`"Power gain"="Voltage gain"xx"Current gain"`
`"Voltage gain"=("Power gain")/("Current gain")=(300)/(50)=6`
