In a transistor circuit the base current changes from `30 mu A` to `90 mu A`. If the current gain of the transistor is `30`, the change in the collector current is.

A

`4 mA`

B

`2 mA`

C

`3.6 mA`

D

`1.8 mA`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta I_(B)=DeltaI_(E)- Delta I_(C)` and `beta = (Delta l_(c))/(Delta l_(B))`.
