In a transistor , the collector current varies by 0.49mA and emitter current varies by 0.50mA current gain `beta` measured is

A

49

B

150

C

99

D

100

Text Solution

Verified by Experts

The correct Answer is:
A
`beta=(DeltaI_(C))/(DeltaI_(B))=(DeltaI_(C))/(DeltaI_(E)-DeltaI_(C))=(0.49mA)/(0.50mA-0.49mA)=(0.49)/(0.01)=49`
