Measurement and Instrumentation The resistance of a circuit is found by measuring current flowing and the power fed into the circuit. If the limiting errors in the measurement of power and current are ± 1.5% and ± 1.0% respectively, the limiting error in the measurement of resistance ± 3.5% ± 1% ± 1.5% ± 2.5% ± 3.5% ± 1% ± 1.5% ± 2.5% ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation Potentiometer method of DC voltage measurement is more accurate than direct measurement using a voltmeter because It uses centre zero galvanometer instead of voltmeter. It loads the circuit moderately. It loads the circuit to maximum extent. It does not load the circuit at all. It uses centre zero galvanometer instead of voltmeter. It loads the circuit moderately. It loads the circuit to maximum extent. It does not load the circuit at all. ANSWER DOWNLOAD EXAMIANS APP
