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 ± 2.24) A (400 ± 1) A (400 ± 1.5) A (400 ± 3) A (400 ± 2.24) A (400 ± 1) A (400 ± 1.5) A (400 ± 3) A ANSWER DOWNLOAD EXAMIANS APP

Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It loads the circuit moderately. It does not load the circuit at all. It uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It loads the circuit moderately.
