Electrical cable Electrical cable 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
Mechanical–electrical analogies Mechanical–electrical analogies Mechanical–electrical analogies are the representation of mechanical systems as electrical networks. At first, such analogies were used in reverse to help explain electrical phenomena in familiar mechanical terms. James Clerk Maxwell introduced analogies of this sort in the 19th century. However, as electrical network analysis matured it was found that certain mechanical problems could more easily be solved through an electrical analogy. Theoretical developments in the electrical domain that were particularly useful where the representation of an electrical network as an abstract topological diagram (the circuit diagram) using the lumped element model and the ability of network analysis
