The approximate ratio of resistance in the forward and reverse biase of the `PN-` junction diode is

A

`10^(7):1`

B

`10^(-2):1`

C

`1:10^(-4)`

D

`1:10^(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Resistance in forward biasing `R_(f r)~~10^(5)Omega` and resistance in reverse biasing `Rw~~10^(5) Omega implies (R_(f r))/(R_(Rw)) =1/(10^(4))`
