What is the difference between cable and wire?

what is the difference between cable and wire? In simple terms, a wire is a single conductor, while a cable is a group of wires wrapped together for protection and efficiency. Both are essential in electrical and electronic systems, but they are used for different purposes depending on the application.

1. Wire

A wire is a single electrical conductor, usually made of copper or aluminum. It can be solid or stranded and may be bare or covered with insulation.

Key points about wire:

Single conductor

Simple structure

Used for basic electrical connections

Common in internal wiring and electronics

Example: A single copper conductor used inside a circuit board.

2. Cable

A cable consists of two or more wires bundled together and enclosed in a protective outer sheath. Each wire inside the cable may have its own insulation, and the cable jacket provides additional mechanical and environmental protection.

Key points about cable:

Multiple conductors

More complex structure

Provides better protection

Used for power distribution, communication, and signal transmission

Example: Power cables, Ethernet cables, and coaxial cables.
