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 ± 2.4% ± 1% ± 1.4% ± 3.4% ± 2.4% ± 1% ± 1.4% ± 3.4% ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A single phase load is connected between R and Y terminals of a 415 V, symmetrical, 3-phase, 4 wire system with phase sequence RYB. A wattmeter is connected in the system as shown in figure. The power factor of the load is 0.8 lagging. The wattmeter will read + 597 W. - 597 W. + 795 W. - 795 W. + 597 W. - 597 W. + 795 W. - 795 W.
