Measurement and Instrumentation It can be stated that CT operates with considerably lower flux density than a PT No generalisation can be made with regard to the flux densities in CT and PT CT operates at almost the same flux density as a PT CT operates with a higher flux density than PT CT operates with considerably lower flux density than a PT No generalisation can be made with regard to the flux densities in CT and PT CT operates at almost the same flux density as a PT CT operates with a higher flux density than PT ANSWER DOWNLOAD EXAMIANS APP
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 ± 2.5% ± 1.5% ± 3.5% ± 1% ± 2.5% ± 1.5% ± 3.5% ± 1% ANSWER DOWNLOAD EXAMIANS APP
