Extension cord

An extension cord is a flexible electrical cable with a plug on one end and one or more sockets on the other, designed to extend the reach of a power source to devices that are located farther away from a wall outlet. It is commonly used in homes, offices, and outdoor settings to power appliances, tools, or electronics when fixed outlets are not conveniently located. Extension cords come in various lengths, thicknesses, and power capacities, with heavier-duty cords built to handle high-wattage devices like heaters or power tools. Many modern extension cords include safety features such as surge protection, grounding plugs, and child-protective covers. While they are practical and widely used, it is important to use them carefully—avoiding overloading, keeping them away from water, and not using damaged cords—to prevent electrical hazards like short circuits or fires.
