A transistor is operated in common emitt...

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 `300 muA` produces a change in the collector current from `10 mA` to `20 mA`. The current gain is

A

75

B

100

C

25

D

50

Text Solution

Verified by Experts

The correct Answer is:
D

`beta=(DeltaI_(C))/(DeltaI_(B))=((20-10)mA)/((300-100)mA)=50`
