IA Rugby.com The purpose of insulation around a conductor is much like that of a pipe carrying water, and ohm’s law of electricity can be more easily understood by a comparison with water flow. In Fig. 1 we show this comparison. pressure on water from a pump causes flow along the pipe (Fig. 1a). If the pipe were to spring a leak, you’d waste water and lose some water …
