Measurement and Instrumentation The resistance of a circuit is measured from the relation R= P/I2, where P is the power fed into the circuit and I is the current flowing through it. If the limiting errors in the measurement of power and current are respectively ± 1.0% and ± 1.0%, then what will be the limiting error in measurement of resistance ? ±3.5% ± 1.5% ± 3.0% ±0.5% ±3.5% ± 1.5% ± 3.0% ±0.5% ANSWER DOWNLOAD EXAMIANS APP
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% ± 1.4% ± 2.4% ± 3.4% ± 1% ± 1.4% ± 2.4% ± 3.4% ANSWER DOWNLOAD EXAMIANS APP
