    If only 2% of the main current is to be passed through a galvanometer of resistance G, then the resistance of shunt will be                                                         [MP PMT/PET 1998]

    A)                    \[\frac{G}{50}\]

    B)                                      \[\frac{G}{49}\]

    C)                    \[50\,G\]                        

    D)            \[49\,G\]

    Correct Answer: B

    Solution :

                 \[{{i}_{g}}=2%\] of \[i=\frac{i}{50}\]Þ \[S=\frac{G}{(n-1)}=\frac{G}{(50-1)}=\frac{G}{49}\]
