Potentiometer method of dc voltage measurement is more accurate than direct measurement using a voltmeter because
it loads the circuit to maximum extent
it loads the circuit moderately
it does not load the circuit at all
it uses centre zero galvanometer instead of Voltmeters
Correct Answer:
it does not load the circuit at all
Explanation:
Since the circuit is not loaded, the accurate value of dc voltage is measured.
