Versor

The supply is a complex quantity in an electro-technical literature to be found in the area of ​​complex AC bill spelling. He can stand for a rest in the complex plane ( time-independent ) Phasor, but a ( time-dependent ) rotation pointer is also called supply.

The complex number is represented by the angular Versorzeichen by

And read as: is equal to supply. Here are the magnitude and the argument of the complex number and the imaginary unit.

This notation avoids the exponents and are arguing the same line and write the same character size as the amount.

A rotating pointer is a time-dependent quantity, which can be represented in the complex plane by a pointer to the length, which rotates at the angular speed around the zero point. As a supply of the rotating pointer is written in the form.

The factor therein is a stationary pointer is also called amplitude or complex phasor.
