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

  1. A10
  2. B10−610^{-6}
  3. C10610^{6}
  4. D100

Correct answer

B. 10−610^{-6}

Step-by-step solution

Forward bias resistance =\frac{\Delta \mathrm{V}}{\Delta\mathrm{I}}=\frac{0.1}{10 \times 10^{-3}}=10 \Omega Reverse bias resistance =1010−6=107Ω=\frac{10}{10^{-6}}=10^{7} \Omega Ratio of resistances = Forward bias resistance  Reverse bias resistance =10−6=\frac{\text{ Forward bias resistance }}{\text{ Reverse bias resistance }}=10^{-6}
