What is a Wire?
Wire refers to a single, usually cylindrical, strand or rod of metal which is used to carry electricity and telecommunications signals. Wire is commonly formed by drawing metal through a hole in a die or draw plate. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multi-stranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.
Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers.
