    In a reverse biased diode when the applied voltage changes by 1 V, 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 \[=\frac{\Delta V}{\Delta I}\] \[=\frac{1}{0.5\times {{10}^{-6}}}\] \[=2\times {{10}^{6}}\,\Omega \]
