Three-prong outlets are electrical sockets designed to accommodate plugs with three metal prongs. The three prongs consist of a live wire, a neutral wire, and a ground wire. This design enhances safety by providing a path for electrical current to return safely to the ground, reducing the risk of electric shock or fire. These outlets are commonly found in homes and businesses, especially in areas where high-powered appliances are used, such as kitchens and workshops. The ground prong is typically longer than the other two, ensuring that the device is grounded before power is supplied, which is a crucial safety feature in modern electrical systems.
