An electrical outlet is an opening or series of openings connected to a wired power source meant to power electrical equipment and components.It is one of the most commonly used items in a home or building and can be found nearly universally, although many countries have different standards or voltages.ost household electronic components get their power from a cord that is plugged into the outlet. The plug of the component transfers power from the electrical outlet to the device requiring it. Another wire then takes the electricity back to its original location.
