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

View answer and explanation

Correct option: C

\mathrm{\Omega }

Option C (10

\mathrm{\Omega }

) is correct because the forward bias resistance is calculated using Ohm's law:

R = \frac{{\Delta V}}{{\Delta I}}
