An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current.
The term cable originally referred to a nautical line of specific length where multiple ropes are combined to produce a strong thick line that was used to anchor large ships.
As electric technology developed, people changed from using bare copper wire to using groupings of wires and various sheathing and shackling methods that resembled the mechanical cabling so the term was adopted for electrical wiring. In the 19th century and early 20th century, electrical cable was often insulated using cloth, rubber or paper.
Plastic materials are generally used today, except for high-reliability power cables. The term has also come to be associated with communications because of its use in electrical communications.
