A phasor is a ______ vector.

Asked in GSEB Board March 2016 · Phase relationships and phasors

Answer: (3) rotating

Step-by-step solution

A phasor represents a sinusoidal quantity such as v=V₀ sin ω t.

It is a vector of length V₀ that rotates anticlockwise about the origin with angular speed ω.

Its projection on the vertical axis at time t is V₀ sin ω t, the instantaneous value.

The angle between two phasors gives the phase difference between the quantities they represent.

So a phasor is a rotating vector.
