Vector
In mathematics and physics a vector (also known as a
Euclidian vector) is a geometric entity endowed with both
length and direction. In physics, Euclidian vectors are used
to represent physical quantities which have both magnitude
and direction, such as force, in contrast to scalar quantities,
such as pressure, which have no direction. In the energy
distribution industry, a vector represents a magnitude
(voltage, current, impedance) and a direction (phase angle
with respect to a reference).
