A power outlet, also known as an electrical socket, is a device that allows electrical appliances to connect to the electrical supply in a building. It typically consists of one or more openings where a plug can be inserted, providing a pathway for electricity to flow from the wall to the appliance. Power outlets come in various types and configurations, depending on the country and electrical standards. Most power outlets are designed to accommodate standard plugs, which can power devices like computers, televisions, and kitchen appliances. Safety features, such as circuit breakers and ground fault circuit interrupters (GFCIs), are often included to prevent electrical hazards. Proper installation and maintenance of power outlets are essential for ensuring safe and efficient use of electricity.
