    When the voltage drop across a P-N Junction diode is increased from \[0.65\]to \[0.70,\]the change in the diode current is\[5\text{ }mA\]. The dynamic resistance of diode is :-

    A)  \[10\Omega \]            

    B)  \[20\Omega \]

    C)  \[50\Omega \]                

    D)  \[80\Omega \]

    Correct Answer: A

    Solution :

    \[R=\frac{\Delta V}{\Delta I}=\frac{0.70-0.65}{5mA}-\frac{0.05}{5mA}=10\Omega \]
