I v//s V curve for a non Ohmic resistanc...

`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

Dynamic resistance `R = (dv)/(dI) = (1)/(dI//dv) = (1)/(slope)`
At Pt a slope is min So R is max .
