When the forwward bias voltage of a diode is changed from `0.6` V to `0.7` V the current changes from 5 mA to 15 mA. Then its forward bias resistance is

A

100 `Omega`

B

200 `Omega`

C

300 `Omega`

D

400 `Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`R_f = (DeltaV)/(DeltaI)=(2-0.8)/(4xx10^(-3)) = (1.2xx10^3)/4 = 300 Omega`
