    A 2V battery is connected across AB as shown in the figure. The value of the current supplied by the battery when in one case battery's positive terminal is connected to A and in other case when positive terminal of battery is connected to B will respectively be:

    A) 0.4 A and 0.2 A

    B)        0.2 A and 0.4 A

    C) 0.1 A and 0.2 A

    D)        0.2A and 0.1 A

    Correct Answer: A

    Solution :

    [a] When positive terminal connected to A then diode D, is forward biased, current, \[I=\frac{2}{5}=0.4\,\,A\] When positive terminal connected to B then diode \[{{D}_{2}}\] is forward biased, current, \[I=\frac{2}{10}=0.2\,\,A\]
