The answer to 'what is outlet' is an electrical outlet, also known as a power outlet or wall socket. An outlet is a point on an electrical wiring system where devices can be connected to the electrical power supply. Outlets provide a safe and convenient way to connect lamps, appliances, electronics, and other electrical equipment to the home's electrical system.
Outlets are typically installed in the walls, floors, or ceilings of a home and are connected to the home's electrical wiring. They come in a variety of shapes, sizes, and configurations to accommodate different types of electrical plugs and devices. The most common type of outlet in North America is the standard 120-volt, 15-amp or 20-amp receptacle with two flat parallel slots and a round ground slot.
