What does a phasor represent in electrical engineering?

Show Answers

A vector illustrating the magnitude and phase angle of an alternating current or voltageA line indicating the size and direction of a fluctuating electrical quantityA color-coded marker used to differentiate phases in a three-phase electrical systemA device designed to measure the phase angles in an unbalanced three-phase loadNone of the above

Explanation

A phasor is a vector that graphically expresses both the magnitude and phase angle of an alternating electrical quantity, such as current or voltage. While it shows phase information, options involving color markers or measuring instruments do not define what a phasor is.
