Measurement and Instrumentation The total current I = I1 + I2 in a circuit is measured as I1 = 150 ± 1A , I2 = 250 ± 2A, where the limits of error are as standard deviations. I is measured as (400 ± 3) A (400 ± 2.24) A (400 ± 1) A (400 ± 1.5) A (400 ± 3) A (400 ± 2.24) A (400 ± 1) A (400 ± 1.5) A 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 ± 1.4% ± 2.4% ± 1% ± 3.4% ± 1.4% ± 2.4% ± 1% ± 3.4% ANSWER DOWNLOAD EXAMIANS APP
