    A 50 ohm galvanometer gets full scale deflection when a current of 0.01 A passes through the coil.  When it is converted to a 10 A ammeter, the shunt resistance is [Orissa JEE 2003]

    A)          0.01 W

    B)                        0.05 W

    C)         2000 W

    D)                        5000 W

    Correct Answer: B

    Solution :

                                             \[{{i}_{g}}=i\frac{S}{G+S}\]Þ\[\frac{0.01}{10}=\frac{5}{50+S}\]Þ \[S=\frac{50}{999}=0.05\Omega \].
