Electrical plugs are devices used to connect electrical appliances to a power source. They typically consist of metal prongs that fit into corresponding sockets, allowing electricity to flow from the outlet to the appliance. Plugs come in various shapes and sizes, depending on the country and the specific electrical standards in place. Different types of plugs are designed for different voltages and currents, ensuring safety and compatibility. Common plug types include Type A, Type B, and Type C, each with unique configurations. Understanding these variations is essential for using electrical devices safely and effectively across different regions.
