If collector current is 120 mA and base ...

If collector current is 120 mA and base current is 2 mA and resistance gain is 3, what is power gain ?

A

180

B

10800

C

`1.8`

D

18

Text Solution

Verified by Experts

The correct Answer is:
B
Current gain `beta =(I_(C ))/(I_(B))=((120 mA))/((2 mA))=60`
Power gain = Resistance gain `xx beta^(2)`
`= (3)xx(60)^(2)=10800`
