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

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

Options

A $100$
B ${10}^{6}$
C ${10}^{- 6}$
D $10$

Correct answer

C. ${10}^{- 6}$

Step-by-step solution

Forward bias resistance

{R}_{1} = \dfrac{0.8 - 0.7}{\left(20 - 10\right) \times {10}^{- 3}} = \dfrac{0.1}{10 \times {10}^{- 3}} = 10Ω

.

Reverse bias resistance

{R}_{2} = \dfrac{10}{{10}^{- 6}} = {10}^{7}Ω

\dfrac{{R}_{1}}{{R}_{2}} = {10}^{- 6}
