    When the forward bias voltage of a diode is changed from \[0.6\text{ }V\] to \[0.7\text{ }V,\] the current changes from \[5\text{ }mA\] to\[15\text{ }mA\]. Then its forward bias resistance is

    A)  \[0.01\,\Omega \]

    B)  \[0.1\,\Omega \]

    C)  \[10\,\Omega \]

    D)  \[100\,\Omega \]

    Correct Answer: C

    Solution :

    [c] Forward bias resistance \[=\frac{\Delta V}{\Delta I}\] \[=\frac{(0.7-0.6)V}{(15-5)mA}=\frac{0.1}{10\times {{10}^{-3}}}=10\Omega .\]
