    A galvanometer of \[100\,\Omega \] resistance gives full scale deflection when 10 mA of current is passed. To convert it into 10 A  range ammeter, the resistance of the shunt required will be                                               [MP PMT 1985]

    A)                    \[-10\,\Omega \]

    B)                                      \[1\,\Omega \]

    C)                    \[0.1\,\Omega \]        

    D)            \[0.01\,\Omega \]

    Correct Answer: C

    Solution :

                 \[S=\frac{{{i}_{g}}G}{i-{{i}_{g}}}=\frac{100\times 0.01}{(10-0.01)}=\frac{1}{10}=0.1\Omega \]
