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 `200 muA` produces a change in the collector current of 5mA to 10 mA. The current gain is

A

100

B

150

C

75

D

50

Text Solution

Verified by Experts

The correct Answer is:
D
Current gain, `beta=(DeltaI_C)/(DeltaI_B)=((10-5)xx10^(-3))/((200-100)xx10^(-6))=50`
