In a n-p-n transistor circuit, the collector current is 10 mA. 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
Here, `I_(C )=95% I_(E)=0.95I_(E )`
`therefore 10=0.95I_(E ) (because (I_(C )=10mA)`
`therefore I_(E )=(10)/(0.95)=(1000)/(95)=10.526`
`therefore I_(E )~~10.53mA`
Here, `I_(B)=5% I_(E )=10.53xx(5)/(100)=0.5265mA`
`therefore I_(B) ~~ 0.53mA`
