In an n-p-n transistor circuit, the collector current is 10mA. If 90% of the electrons emitted reach the collector, the emitter current `(I_(E ))` and base current `(I_(B))` are given by

A

`I_(E) = -1mA, I_(B) = 9mA`

B

`I_(E) = 9mA, I_(B) = 1mA`

C

`I_(E) = 1mA, I_(B) = 11mA`

D

`I_(E) = 11 mA, I_(B) = 1mA`

Text Solution

Verified by Experts

The correct Answer is:
D
`I_(E) = I_(C) = I_(B) = 10mA + 1mA = 11mA`
