Measurement and Instrumentation Consider the following statement - 1. The compensating coil of a low power factor wattmeter compensates the effect of the impedance of the current coil. 2. The compensating coil of a low power factor wattmeter compensates the effect of the impedance of the voltage coil circuit. 1 is true but 2 is false. Both 1 and 2 are true. Both 1 and 2 are false. 1 is false but 2 is true. 1 is true but 2 is false. Both 1 and 2 are true. Both 1 and 2 are false. 1 is false but 2 is true. ANSWER DOWNLOAD EXAMIANS APP
Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then Y is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. X is more sensitive. Both X and Y are equally sensitive. Y is more sensitive. It would not be possible to assess the sensitivity on the basis of the given data. X is more sensitive. Both X and Y are equally sensitive. ANSWER DOWNLOAD EXAMIANS APP
