A power outlet is a device that is used to connect alternating current supplied by municipal electric power to enable household appliances to be electrified with portable small devices. The power socket is a female connector with slots or holes, which is used to insert the power plug with rod or copper shaped protrusion to transmit electric power through the plug to the electrical appliance.
The general socket is designed to be a plug of the same specification. It will not be inserted. There will be some bar shaped protrusion on the part of the socket, with holes in the plug.
