Question

In a reverse biased diode when the applied voltage changes by 1 V, the current is found to change by 0.5 µA. The reverse bias resistance of the diode is ______.

Options

• 2 × 10⁵ W

• 2 × 10⁶ W

• 200 Ω

• 2 Ω

Answer 1

In a reverse biased diode when the applied voltage changes by 1 V, the current is found to change by 0.5 µA. The reverse bias resistance of the diode is 2 × 10⁶ W.

Explanation:

Reverse resistance

= `(Delta"V")/(Delta"I")`

= `1/(0.5xx10^-6)`

= 2 × 10⁶ Ω
