Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It does not load the circuit at all. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter.
