    To converted a moving coil galvanometer (MCG) into a voltmeter

    A) a high resistance R is connected in parallel with MCG

    B) a low resistance R is connected in parallel with MCG

    C) a low resistance R is connected in series with MCG

    D) a high resistance R is connected in series with MCG

    Correct Answer: D

    Solution :

    To convert a moving coil galvanometer into a voltmeter, it is connecting with a high resistance in series. The voltmeter is connected in parallel to measure the potential difference. As the resistance is high, the voltmeter itself does not consume current.
