This type of winding is used to Increase the thermal stability Reduce the inductance of winding Reduce the tolerance Double the power rating of the resistor Increase the thermal stability Reduce the inductance of winding Reduce the tolerance Double the power rating of the resistor ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation A resistance is measured by the voltmeter-ammeter method employing dc excitation and a voltmeter of very high resistance connected directly across the unknown resistance. If the voltmeter and ammeter reading are subject to maximum possible errors of ± 2.4 % and ± 1.0 % respectively, then the magnitude of the maximum possible percentage error in the value of resistance deduced from the measurement is nearly ± 3.4% ± 1.4% ± 1% ± 2.4% ± 3.4% ± 1.4% ± 1% ± 2.4% ANSWER DOWNLOAD EXAMIANS APP
