`I v//s V` curve for a non Ohmic resistance is shown. The dynamic resistance is maximum at point

A

`a`

B

`b`

C

`c`

D

same for all

Text Solution

Verified by Experts

The correct Answer is:
C
Dynamic rasistance `R=(dv)/(di)=(1)/(di//dv)=(1)/(slope)`
at pointt. `c`, slope is min, So `R` is max
