• National High Magnetic Field Laboratory - Current Flow Tutorial
  Current Flow This tutorial illustrates how the flow of water through a system of pipes can be used to understand the flow of current through an electric circuit. Here blue particles represent the flow of water, moving as electrons do through a circuit to create electricity. The rate of water flow, defined as the volume of the fluid moving past a certain point in a fixed amount of time, is comparable to the rate of charge passing a point in a circuit (electric current), which is measured in amperes (coulombs/second).
