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 ? ± 1.5% ±3.5% ±0.5% ± 3.0% ± 1.5% ±3.5% ±0.5% ± 3.0% ANSWER DOWNLOAD EXAMIANS APP
