Measurement and Instrumentation To measure 5 volts, if one selects a 0-100 volt range voltmeter which is accurate with in ± 1%, then the error in this measurement may be up to ± 2.5% ± 7.5 % ± 20% ± 1.5% ± 2.5% ± 7.5 % ± 20% ± 1.5% ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation The total current I = I1 + I2 in a circuit is measured I1 = 150 ± 3A , I2 = 250 ± 4 A, where the limits of error are given as standard deviations. I is measured as (400 ± 2.24) A (400 ± 1) A (400 ± 3) A (400 ±5) A (400 ± 2.24) A (400 ± 1) A (400 ± 3) A (400 ±5) A ANSWER DOWNLOAD EXAMIANS APP
