    In the circuit shown \[P\ne R\], the reading of the galvanometer is same with switch S open or closed. Then                                                                            [IIT-JEE (Screening) 1999]

    A)                    \[{{I}_{R}}={{I}_{G}}\]

    B)                    \[{{I}_{P}}={{I}_{G}}\]      

    C)                    \[{{I}_{Q}}={{I}_{G}}\]

    D)                    \[{{I}_{Q}}={{I}_{R}}\]      

    Correct Answer: A

    Solution :

                 Reading of galvanometer remains same whether switch S is open or closed, hence no current will flow through the switch i.e. R and G will be in series and same current will flow through them. \[{{I}_{R}}={{I}_{G}}\].
