A phasor represents-

1. The magnitude and the direction of a quantity.
2. The width of a quantity.
3. The phase angle.
4. The magnitude of a quantity.

Answer: A. The magnitude and the direction of a quantity

## A phasor represents the magnitude and the direction of a quantity.

Solution

When we are representing two or more sinusoidal waves having the same frequency in a mathematical form it is difficult to visualize the phasor or angular difference between these waveforms. This can be overcome by representing this sinusoidal wave graphically within spatial or phasor domain form by using the rotating vector method.

The rotating vector or the phase vector is a scaled line. The length of the phase vector represents either the peak amplitude or RMS value and direction of the AC quantity for a given instant of time.

Hence, a phasor represents the magnitude and the direction of a quantity. Option A is the correct answer.
