In `NPN` transistor the collector current is `10mA`. If `90%` of electrons emitted reach the collector, the

A

emitter current will be `9mA`

B

emitter current will be `11.1mA`

C

base current will be `0.1mA`

D

base current will be `0.01mA`

Text Solution

Verified by Experts

The correct Answer is:
