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