Definition, Meaning & Synonyms

phasor

noun

/ˈfeɪzər/

Definition

A phasor is a complex number representing a sinusoidal variation of a quantity, used primarily in electrical engineering and physics to simplify calculations involving alternating current (AC) circuits.

Examples

The engineer used a phasor to calculate the impedance in the AC circuit.
By using phasors, we can easily determine the phase difference between two alternating signals.
The concept of phasors simplifies the analysis of complex AC systems.

Meaning

Phasors are used to analyze the amplitude and phase of sinusoidal signals and represent them in a way that makes calculations easier, especially when dealing with periodic signals.
