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

50

B

75

C

100

D

25

Text Solution

Verified by Experts

The correct Answer is:
A
The current gain `beta =(DeltaI_C)/(DeltaI_B) = (100mA)/(200muA) = (10xx10^3)/200 = 50`
