What is the distinguishing characteristic of an electrical cable?

The distinguishing characteristic of an electrical cable is that it consists of two or more conductors inside a single covering. This feature is fundamental to the definition of a cable, as it differentiates it from other types of wiring. Cables are designed to carry electrical signals or power through multiple conductors, which can include different configurations for communication, power distribution, and other applications.

In essence, having multiple conductors allows for various functionalities, such as enabling parallel power transmission or facilitating communication between devices. The common covering or insulation helps protect the conductors from physical damage and environmental factors, ensuring safe and efficient operation.

Other characteristics, like having multiple sheaths, a single conductor, or a higher voltage rating, are not exclusive to the definition of an electrical cable and could apply to different types of wiring or cables. The combination of multiple conductors within a single protective casing is what primarily identifies a cable in electrical contexts.
