    In a reverse biased diode when the applied voltage changes by 1V, the current is found to change by 0.5 \[\mu \]A. The reverse bias resistance of the diode is

    A) \[2\times {{10}^{5}}\Omega \]

    B)  \[2\times {{10}^{6}}\Omega \]

    C)  \[200\,\Omega \]

    D)  \[2\,\Omega \]

    Correct Answer: B

    Solution :

    Reverse resistance \[=\frac{\Delta V}{\Delta I}=\frac{1}{0.5\times {{10}^{-6}}}\] \[=2\times {{10}^{6}}\Omega \]
