Measurement and Instrumentation If two meters X and Y require 40 mA and 50 mA respectively, to give full scale deflection, then

Both X and Y are equally sensitive.
It would not be possible to assess the sensitivity on the basis of the given data.
Y is more sensitive.
X is more sensitive.

parallel.
perpendicular.
inclined at 30o.

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.

Both 1 and 2 are true.
1 is true but 2 is false.
1 is false but 2 is true.
Both 1 and 2 are false.
