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 loads the circuit moderately. It does not load the circuit at all. It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It loads the circuit moderately. It does not load the circuit at all. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A variable w is related to three other variables x, y and z as w = xy/z. The variables are measured with meters of accuracy ± 0.5% reading, ± 1% of full scale value and ± 1.5% reading. The actual readings of the three meters are 80, 20 and 50 with 100 being the full scale value for all three. The maximum uncertainty in the measurement of w will be ± 5% ± 8% ± 7% ± 6% ± 5% ± 8% ± 7% ± 6% ANSWER DOWNLOAD EXAMIANS APP
