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 does not load the circuit at all. It loads the circuit to maximum extent. It uses centre zero galvanometer instead of voltmeter. It loads the circuit moderately.
