    A milliammeter of range 10 mA has a coil of resistance 1 W.  To use it as voltmeter of range 10 volt, the resistance that must be connected in series with it, will be         [KCET 2001]

    A)         999 W                              

    B)         99 W

    C)         1000 W                            

    D)         None of these

    Correct Answer: A

    Solution :

                                             \[R=\frac{V}{{{i}_{g}}}-G=\frac{10}{10\times {{10}^{-3}}}-1=999\Omega \].
