When the forward 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

Options

A. `0.01Omega`
B. `0.1Omega`
C. `10Omega`
D. `100Omega`

Answer

C

Explanation

Forward bias resitance `=(DeltaV)/(DeltaI)`
`=(0.7-0.6)/((15-5)xx10^(-3))`
`=(0.1)/(10xx10^(-3))=10Omega`
