In the `CB` mode of a transistor, when the collector voltage is changed by `0.5` volt. The collector current changes by `0.05 mA`. The output resistance will be

A

`10kOmega`

B

`20kOmega`

C

`5kOmega`

D

`2.5kOmega`

Text Solution

Verified by Experts

The correct Answer is:
A
`R=(DeltaV_(c ))/(DeltaI_(C ))=(0.5)/(0.05xx10^(-3))=10^(-4)Omega=10kOmega`
