    Why doesn't a bulb glow even if the correct connections are made?
    (i) Battery is dead.
    (ii) Filament is broken.
    (iii) Switch is closed.

    A)  Only(i)       

    B)  Only(ii)

    C)  Only(iii)      

    D)  Only (i) and (ii)

    Correct Answer: D

    Solution :

    If a battery is dead, the bulb does not get the supply of energy. So, the bulb does not glow. If the filament is broken in the bulb, it does not glow. But if a switch is closed, then the bulb glows as current flows through the circuit.
