    In the following Wheatstone bridge \[P/Q=R/S\]. If key K is closed, then the galvanometer will show deflection [CPMT 1999]

    A)                    In left side

    B)                    In right side

    C)                    No deflection

    D)                    In either side

    Correct Answer: D

    Solution :

                 Pressing the key does not disturb current in all resistances as the bridge is balanced. Therefore, deflection in the galvanometer in whatever direction it was, will stay.
