In transistor, a change of `8.0 mA` in the emitter current produces a change of `7.8 mA` in the collector current. What change in the base current is necessary to produce the same change in the collector current ?

A

`50 muA`

B

`100 muA`

C

`150 muA`

D

`200 muA`

Text Solution

Verified by Experts

The correct Answer is:
B
`Deltai_(e)=Deltai_(c)+Deltai_(b)`
`implies 8=7.8+Deltai_(b) implies Deltai_(b)=0.2 mA=200 muA`
