    A galvanometer of 10 ohm resistance gives full scale deflection with 0.01 ampere of current. It is to be converted into an ammeter for measuring 10 ampere current. The value of shunt resistance required will be     [MP PET 1984]

    A)                    \[\frac{10}{999}\]ohm

    B)                                      0.1 ohm

    C)                    0.5 ohm                          

    D)            1.0 ohm

    Correct Answer: A

    Solution :

                 \[S=\frac{{{i}_{g}}G}{i-{{i}_{g}}}=\frac{10\times 0.01}{10-0.01}=\frac{10}{999}ohm\]
