Reverse Bias Resistance of Diode

In a reverse biased diode when the applied voltage changes by \(5 \text{V}\), the current is found to change by \(2 \mu\text{A}\). The reverse bias resistance of the diode is:
\(10^6 \Omega\)
\(2 \times 10^6 \Omega\)
\(5 \times 10^6 \Omega\)
\(2.5 \times 10^6 \Omega\)

Solution:

Reverse resistance is given by \(R = \frac{\Delta V}{\Delta I}\). Substituting the values, \(R = \frac{5 \text{V}}{2 \times 10^{-6} \text{A}} = 2.5 \times 10^6 \Omega\).
