AC POWER SYSTEM IEEE PAPER 2022
Alternating current (AC) power is the standard electricity that comes out of power outlets and is defined as a flow of charge that exhibits a periodic change in direction In ac circuits there are three kinds of power:real, reactive, and apparent power. The kind of power that exists in purely resistive circuits is what is called real power. Real power is power that is dissipated in the form of heat and is measured in watts Alternating current (AC) is an electric current that periodically reverses its direction, in contrast to direct current (DC) which only flows in a single direction which cannot change sporadically.
