    A galvanometer has resistance of \[7\,\Omega \] and gives a full scale deflection for a current of 1.0 A. How will you convert it into a voltmeter of range 10 V        [MP PMT 1999]

    A)                    \[3\,\Omega \] in series  

    B)            \[3\,\Omega \] in parallel

    C)                    \[17\,\Omega \] in series

    D)            \[30\,\Omega \] in series

    Correct Answer: A

    Solution :

                 By connecting a series resistance            \[R=\frac{V}{{{i}_{g}}}-G=\frac{10}{1}-7=3\,\Omega \]
