In an n-p-n circuit transistor, the collector current is 10 mA. If 80 % electron emitted reach the collector then

A

The emitter current will be `2.5 mA`

B

The emitter current will be `12.5 mA`

C

The base current wil be `2.5 mA`

D

The base current will be `22.5 mA`

Text Solution

Verified by Experts

The correct Answer is:
C
`I_(E ) = ((100)/(80)) I_(C ) = ((100)/(80)) (10) = 12.5 mA`
`I_(B) = I_(E ) - I_(C ) = 12.5 - 10 = 2.5 mA`
