  1. Question 1

    Q1. What is the primary reason for using a high resistance in series with a galvanometer when converting it to a voltmeter?

    • A) To increase the sensitivity of the voltmeter
    • B) To decrease the resistance of the voltmeter
    • C) To limit the current through the galvanometer
    • D) To measure high voltages

    Answer: To limit the current through the galvanometer

    Explanation: The high resistance limits current through the galvanometer, protecting it. Option B is incorrect as adding resistance increases total resistance.
