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