A transistor is operetaed in common-emitter configuration at `V_(c)=2V` such that a change in the base current from `100mA` to `200mA` produces a change in the collector current from `5mA` to `10mA`. The current gain is

A

`75`

B

`100`

C

`150`

D

`50`

Text Solution

Verified by Experts

The correct Answer is:
D
`beta=(DeltaI_(C ))/(DeltaI_(B))=((10-5)xx10^(-3))/((200-100)xx10^(-6))=50`
