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

Measurement and Instrumentation If two 300V full scale voltmeters V1 and V2 having sensitivities of 100 kOhm/V and 150 kOhm/V are connected in series to measure 500V then V1 = 200V and V2 = 300V. V1 = 250V and V2 = 250V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. V1 = 200V and V2 = 300V. V1 = 250V and V2 = 250V. V1 = 0V and V2 = 0V. V1 = 300V and V2 = 200V. ANSWER DOWNLOAD EXAMIANS APP
