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 `8mA`

B

The emitter current will be `10.53 mA`

C

The base current will be `0.53mA`

D

The emitter current will be `2mA`

Text Solution

Verified by Experts

The correct Answer is:
B, C
Here, `I_c=10mA, I_c=95/100I_(e)`
`:. 10mA=95/100I_(e) or I_(e)=(10xx100)/95=10.53mA`
`I_b=I_(e)-I_c=10.53-10=0.53mA`
