Question

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, the will be `9mA`
B. the base current will be `1mA`
C. the emitter current will be `11mA`
D. both `2` & `3`

Answer 1

Correct Answer - D
`I_(C)=(90)/(100) I_(E) rArr I_(E) =(10)/(9) I_(C)` and `I_(e)=I_(b)+I_(c)`.
