A power socket, also known as an electrical outlet, 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 sockets come in various designs and configurations, depending on the country and electrical standards. Most power sockets are designed to accommodate specific types of plugs, such as Type A or Type B in the United States, and Type C or Type G in Europe and the UK. They are usually mounted on walls and are an essential part of any electrical system, enabling the use of devices like computers, televisions, and kitchen appliances.
