Power supply - Wikipedia
WEBA power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.

WEBJun 2, 2017 · There are two main kinds of current: DC or direct current — a flow of energy like you get from a battery; and AC, or alternating current (like from your wall outlets) — which reverses the direction of electrons, allowing current flow to turn on and off. But that current must be sourced or created.
