  • question_answer
    A milliammeter of range 10 mA has a coil of resistance 1\[\Omega \]. To use it as voltmeter of range 10 volt, the resistance that must be connected in series with it, will be:

    A)  999 \[\Omega \]

    B)  99 \[\Omega \]

    C)  1000 \[\Omega \]

    D)  none of these

    Correct Answer: A

    Solution :

     Given : Range of milliammeter \[{{A}_{ig}}=10mA=10\times {{10}^{-3}}amp.\] Resistance \[G=1\Omega \] Range of voltmeter V = 10 volt The relation for the resistance that must be connected is given by \[=\frac{V}{ig}-G=\left( \frac{10}{10\times {{10}^{-3}}} \right)-1=1000-1=999\Omega \]
