    In which of the following circuits will the bulb glow?                              

    A)       

    B)                    

    C)     

    D)

    Correct Answer: D

    Solution :

    In figure (A), both ends of the bulb are connected to the negative terminal of the cell. So, bulb will not glow while in figure (B) and (C), insulating objects like string and rubber band are used. So, the circuit is incomplete and bulb will not glow. Figure (D) represents the complete circuit with proper connection. Hence, the bulb glows in figure (D).
