    The circuit sown in figure contains two diodes each with a forward resistance of 500 and with infinite backward resistance. If the battery voltage is 6V, the current through 100W resistance (in amperes) is:

    A) zero           

    B)                    0.02

    C) 0.03      

    D)                                    0.036

    Correct Answer: B

    Solution :

    Diode, \[{{D}_{2}}\] is reverse biased Hence current through it is zero. So, current through diode \[{{D}_{1}}\] is passing through \[100\Omega \] is:                 \[=\frac{6}{(\operatorname{Re}sis\tan ce\,of\,{{D}_{1}})+100+150}\,\] \[=\frac{6}{50+100+150}\,=0.02A\].
