Its an interesting story that lays out how we ended up using a seemingly counterintuitive system developed in the 19th century to communicate the size of needles we want to use.
WebThe diameter of a wire is specified by standard gauges in several different systems. Standard gauges are specified by numbers that vary from one system to another. Among the gauge systems in common use are the American wire gauge (AWG), Standard wire gauge (SWG), Washburn & Moen, and Stubs Iron or Birmingham. WebHence Current = Power / Voltage. Current = 3000W/12V = 250A. So the cable needs to have a low resistance to get a low voltage drop, or else it will heat up a lot. For example, if the cable had a resistance high enough to drop 1V across its length, then it will convert electricity, 250A x 1V = 250W, to heat.
Wire gauges may be broadly divided into two groups, the empirical and the geometric. The first includes all the older gauge measurements, notably the Birmingham gauge (B.W.G. or Stubs) and the Lancashire. The origin of the B.W.G. is obscure. The numbers of wire were in common use earlier than 1735. It is believed that they originally were based on the series of drawn wires, No. …
