What information can be obtained from a phasor diagram?
Answer
A phasor diagram illustrates the magnitude and phase angle relationships between various electrical quantities.
A phasor diagram provides a graphical representation of the magnitudes and phase angle relationships among time-varying sinusoidal electrical quantities (such as voltage, current, EMF, and flux) in a machine.
It allows engineers to easily visualize power factor (the angle between voltage and current), voltage drops across impedances, and to perform vector additions required to find terminal voltage or regulation.
