Measurement and Instrumentation A resistance is measured by the voltmeter-ammeter method employing dc excitation and a voltmeter of very high resistance connected directly across the unknown resistance. If the voltmeter and ammeter reading are subject to maximum possible errors of ± 2.4 % and ± 1.0 % respectively, then the magnitude of the maximum possible percentage error in the value of resistance deduced from the measurement is nearly ± 1% ± 3.4% ± 1.4% ± 2.4% ± 1% ± 3.4% ± 1.4% ± 2.4% ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It loads the circuit to maximum extent. It does not load the circuit at all. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It does not load the circuit at all. It loads the circuit moderately. It uses centre zero galvanometer instead of voltmeter. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Kelvin’s double bridge is used to measure low resistance because it has high sensitivity. resistance variation due to temperature. there is no thermo electric emf. effect of contact and lead resistance is eliminated. it has high sensitivity. resistance variation due to temperature. there is no thermo electric emf. effect of contact and lead resistance is eliminated.
