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 will be 9 mA

B

the base current will be 1 mA

C

the emitter current will be 11 mA

D

the base current will be -1 mA.

Text Solution

Verified by Experts

The correct Answer is:
B, C
`I_(c)=10mA`
Base current `I_(b)=10%"of "I_(c)=(10//100)xx10=1mA.`
Emitter current `I_(e)=I_(b)+I_(c)=(1+10)mA=11mA.`
