An electrical cord is a device used to provide power from one source to another. It consists of two components: a flexible cable, or FLEX, and a WIRE. The FLEX is a flexible insulated cable that is used to connect the WIRE to the power source. The WIRE is a metal conductor that carries the electrical current from the power source to the device being powered. Together, the FLEX and WIRE form an electrical cord that is used to provide power to a variety of devices.
