    In the circuit, if the forward voltage drop for the diode is 0.5V, the current will be                                             [UPSEAT 2003]

    A)            3.4 mA

    B)            2 mA

    C)            2.5 mA

    D)            3 mA

    Correct Answer: A

    Solution :

                       The voltage drop across resistance = 8 ? 0.5 = 7.5 V \ Current \[i=\frac{7.5}{2.2\times {{10}^{3}}}=3.4\,mA\]
