Question

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`

Answer 1

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