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 ? ± 3.0% ±0.5% ±3.5% ± 1.5% ± 3.0% ±0.5% ±3.5% ± 1.5% ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation In measurement system, the function of the signal manipulating elements is to change the quantity under measurement to an analogues signal. to perform non liner operation like clipping filtering, chopping and clamping. to perform linear operation like addition and multiplication. change the magnitude of the input signal while retaining its identity. change the quantity under measurement to an analogues signal. to perform non liner operation like clipping filtering, chopping and clamping. to perform linear operation like addition and multiplication. change the magnitude of the input signal while retaining its identity.

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 uses centre zero galvanometer instead of voltmeter. It loads the circuit to maximum extent. It does not load the circuit at all. It loads the circuit moderately.
