    What is the current through an ideal p-n junction diode shown in the figure below?

    A)  Zero                     

    B)  10 mA

    C)  20 mA                

    D)  50 mA

    Correct Answer: C

    Solution :

                    The potential of p-side is more positive than that of n-side hence, diode is in forward biasing. In forward biasing, current flow is possible and \[I=\frac{V}{R}=\frac{(3-1)}{100}\]    \[=20\,\,mA\]
