This white paper defines the differences between Real Power, Reactive Power, and Apparent Power in terms used by the power distribution industry. Here, the relationships between these different types of power are defined and the basic equations for each are given.
The power discussed in this paper is for alternating current (AC) not for direct current (DC), however, the basic definitions are the same. In an AC system, the units of voltage and current used are in RMS.
