Plugs are electrical devices used to connect various appliances and devices to power sources or electrical outlets. They come in different shapes, sizes, and configurations depending on the country’s electrical standards. Plugs usually consist of prongs or pins that fit into corresponding slots in the outlet, allowing the flow of electricity to power the device. Some plugs also include additional features like grounding for safety and compatibility with specific voltage levels. The design of plugs ensures a secure and efficient connection between electrical devices and the power supply.
