    The source voltage is 9V and the source resistance is \[1k\Omega \] The current through the diode is

    A)  3.8 mA                                

    B)  4.2 mA

    C)  0.833mA                            

    D)  8.3mA

    Correct Answer: D

    Solution :

    In this question, the diode is forward biased but its forward bias resistance is not given, but as it is very small, we can get the approximate result. \[i<\frac{9}{1000}=9mA\], where \[{{r}_{f}}\] is forward bias resistance. i has to be slightly less than 9 mA.
