    In a circuit 5 percent of total current passes through a galvanometer.  If resistance of the galvanometer is G then value of the shunt is                                                              [MP PET 2001]

    A)         19 G                                 

    B)         20 G

    C)         \[\frac{G}{20}\]           

    D)         \[\frac{G}{19}\]

    Correct Answer: D

    Solution :

                                             \[\frac{{{i}_{g}}}{i}=\frac{S}{G+S}\] Þ \[\frac{5}{100}=\frac{S}{G+S}\] Þ \[S=\frac{G}{19}\]
