    A galvanometer of\[10\,\Omega \]resistance gives full scale deflection with 0.01 A of current. It is to be converted into an ammeter for measuring 10 A current. The value of shunt resistance will be

    A) \[11\,\Omega \]resistance in series

    B)  100 resistance in series

    C)  990\[\Omega \] resistance in series

    D)  0.10\[\Omega \] resistance in series

    Correct Answer: C

    Solution :

     Resistance \[R=\frac{V}{{{I}_{g}}}-G\] \[=\frac{10}{0.01}-10=1000-10=990\,\Omega \]
