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

`0.01Omega`

B

`0.1Omega`

C

`10Omega`

D

`100Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
The forward bias resistance of the diode is
`r_(fb)=(DeltaV)/(DeltaI)=((0.7-0.6)V)/((15-5)mA)=(0.1V)/(10xx10^(-3)A)=10Omega`
