Aphasoris________?
Correct answer: A. a line which represents the magnitude and phase of an alternating quantity
- A. a line which represents the magnitude and phase of an alternating quantity
- B. a line representing the magnitude and direction of an alternating quantity
- C. a coloured tag or band for distinction between different phases of a 3-phase supply
- D. an instrument used for measuring phases of an unbalanced 3-phase load
Explanation
A phasor is a rotating-vector representation of a sinusoidal quantity, showing both its magnitude and phase angle. Direction alone does not distinguish the phase relationship, so option b is incomplete.
