The V-I characteristic of a diode is shown in the figure. The ratio of forward to reverse bias resistance is:

Answer:

Option B

Explanation:

Forward bias resistance

= $\frac{ΔV}{ΔI}$

= $\frac{0.1}{10\times10^{-3}}$ =10Ω

Reverse bias resistance = $\frac{10}{10^{-6}}$ = 10⁷Ω

Ratio of resistances

= $\frac{Forward bias resistance}{Reverse bias resistance}$ = $10^{-6}$
