A transistor is operated in common emitter configuration at constant collector voltage `V_(c) = 1.5V` such that a change in the base current from `100 mu A` to `150 mu A` produces a change in the collector current from `5mA` to `10 mA`. The current gain `(beta)` is

A

B

75

C

100

D

50

Text Solution

Verified by Experts

The correct Answer is:
C
`beta=(DeltaI_(c))/(DeltaI_(b))=((10-5)xx10^(-3))/((150-100)xx10^(-6))=100`
