    Two electric bulbs, one of 200 V, 40 W and the other of 200V, 100W are connected in a domestic circuit. Then

    A)  the resistance of the bulb of 100 W is more

    B)  the resistance of the bulb of 40 W is more

    C)  the resistance of both the bulbs are same

    D)  they have equal currents through them

    Correct Answer: B

    Solution :

                     The potential of each capacitor is equal to V, when they are in parallel. If they are disconnected and joined in series, then the potential will become V = V + V = 2 V
