The current gain of a transistor in a common base
arrangement in 0.98 . Find the change in collector current corresponding to a
change of 5.0 mA in emitter current . What would be the change in base current?

A

`0.196mA`

B

`2.45mA`

C

`4.9mA`

D

`5.1mA`

Text Solution

Verified by Experts

The correct Answer is:
C
`alpha=0.98=(DeltaI_(C ))/(DeltaI_(C ))`
`0.98=(DeltaI_(C ))/(5)impliesDeltaI_(C )=4.9mA`
