    The net resistance of a voltmeter should be large to ensure that                                                               [MP PMT 1999]

    A)                    It does not get overheated

    B)                    It does not draw excessive current

    C)                    It can measure large potential difference

    D)                    It does not appreciably change the potential difference to be measured

    Correct Answer: D

    Solution :

                 The resistance of voltmeter is too high, so that it draws negligible current from the circuit, hence potential drop in the external circuit is also negligible.
