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

Options:

Answer:

Solution:

Forward bias resistance $R_{1} = \frac{0.8 - 0.7}{(20 - 10) \times 10^{- 3}} = \frac{0.1}{10 \times 10^{- 3}} = 10 Ω$ .

Reverse bias resistance $R_{2} = \frac{10}{10^{- 6}} = 10^{7} Ω$ .

$\frac{R_{1}}{R_{2}} = 10^{- 6}$ .
