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% ± 2.4% ± 3.4% ± 1.4% ± 1% ± 2.4% ± 3.4% ± 1.4% ANSWER DOWNLOAD EXAMIANS APP
