    A galvanometer of resistance \[10\,\,\Omega \]. gives full-scale deflection when 1 mA current passes through it. The resistance required to convert it into a voltmeter reading upto 2.5 V is

    A)  \[24.9\,\,\Omega \]

    B)  \[249\,\,\Omega \]

    C)  \[2490\,\,\Omega \]

    D)  \[24900\,\,\Omega \]

    Correct Answer: C

    Solution :

    Required series resistance                 \[R=\frac{V}{{{I}_{g}}}-G\]                 \[=\frac{2.5}{1\times {{10}^{-3}}}-10\] \[=2490\,\,\Omega \]
