The V-I characteristics of a silicon diode is shown in the figure. The resistance of the diode at $V_D = -10 V$ is

$1.0 × 10^4Ω$ $1.0 × 10^5Ω$ $1.0 × 10^6Ω$ $1.0 × 10^7Ω$ |
$1.0 × 10^7Ω$ |
The correct answer is Option (4) → $1.0 × 10^7Ω$ The resistance of Diode at a particular voltage ($V_D$) is - $R=\frac{V_D}{I}$ [By ohm's law] $=\frac{10}{1μA}=10^7Ω$ |
