A transistor is operated in common emitter configuration at `V_(c)=2 V` such that a change in the base current from `100 muA` to `200 muA` produces a change in the collector current from `5 mA` to `10 mA`. 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))=(5)/(100)xx10^(3)impliesbeta=50`
