The current gain of a common base transi...

The current gain of a common base transistor circuit is 0.96. On changing the emitter current by 10.0 mA, the change in the base current will be

A

9.6 mA

B

0.4 mA

C

19.6 mA

D

24 mA

Text Solution

Verified by Experts

The correct Answer is:
A
Current gain for common base transistor
`alpha=((DeltaI_(C))/(DeltaI_(E)))_(VC)`
Given, `alpha=0.96, DeltaI_(E)=10.0mA`
`0.96=(DeltaI_(C))/(10.0)`
`DeltaI_(C)=0.96xx10.0=9.6mA`
