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 moderately. It loads the circuit to maximum extent. It uses centre zero galvanometer instead of voltmeter. It does not load the circuit at all. It loads the circuit moderately. It loads the circuit to maximum extent. It uses centre zero galvanometer instead of voltmeter. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then X is more sensitive. Both X and Y are equally sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Y is more sensitive. X is more sensitive. Both X and Y are equally sensitive. It would not be possible to assess the sensitivity on the basis of the given data. Y is more sensitive. ANSWER DOWNLOAD EXAMIANS APP
