In an n-p-n transistor circuit, the collector current ia 10 mA. If 90% of the electrons emitted reach the collector.

A

the emitter current, the will be `9mA`

B

the base current will be `1mA`

C

the emitter current will be `11mA`

D

both `2` & `3`

Text Solution

Verified by Experts

The correct Answer is:
D
`I_(C)=(90)/(100) I_(E) rArr I_(E) =(10)/(9) I_(C)` and `I_(e)=I_(b)+I_(c)`.
