What is an extension cord?

An extension cord is a type of electrical cable that is used to plug one device into another that is too far away to be directly plugged into a power source. This is particularly common when working outdoors, such as when using garden tools or when setting up outdoor lighting.

Extension cords come in various lengths, gauges, and types. They can have a grounded plug or not, and they can be used indoors or outdoors. Extension cords can be purchased from stores or made at home.
