Question

Usually phasor diagrams are drawn representing?

(a) RMS value

(b) Peak value

(c) Average value

(d) Instantaneous value

This question was posed to me in a national level competition.

I'm obligated to ask this question of Phasor Diagrams Drawn with RMS Values Instead of Maximum Values topic in portion Alternating Voltage and Current of Basic Electrical Engineering

Answer 1

The correct option is (a) RMS value

The explanation is: Ammeters and voltmeters are calibrated to read the rms value, hence the phasors are drawn representing the rms values.
