    A \[2-V\] battery is connected across the points A and B as shown in the figure given below. Assuming that the resistance of each diode is zero in forward bias, and infinity in reverse bias, the current supplied by the battery when its positive terminal is connected to A, is            

    A)  \[0.2A\]

    B)  \[0.4A\]

    C)  \[0.3A\]

    D)  \[0.1A\]

    Correct Answer: A

    Solution :

    [a] As one of the diodes (the lower one) will be in reverse bias, no current will pass through it, so the effective resistance of the circuit\[=10\,\Omega \].
