In an n-p-n transistor circuit , the collector currents is 10mA . If 95 per cent of the electrons emitted reach the collector, which of the following statements are true?

A

The emitter current will be 8 mA

B

The emitter current will be 10.53 mA.

C

The base current will be 0.53 mA.

D

The base current will be 2 mA.

Text Solution

Verified by Experts

The correct Answer is:
B, C
Given `I_(c)=10mA,I_(c)=95%ofI_(e)`
`therefore10=(95)/(100)I_(e)orI_(e)=(1000)/(95)=10.53mA`
`I_(b)=I_(e)-I_(c)=0.53mA`
