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

A

50

B

75

C

100

D

25

Text Solution

Verified by Experts

The correct Answer is:
A
`beta=(DeltaI_(B))/(DeltaI_(B))=(10mA)/(200muA)=(10xx10^(3))/(200)=50`
