Abstract: Properties of electric circuits such as current, potential, resistance and the relationships among them are often taught using a water analogy. Two things flow in an operating electrical circuit— charges and energy. The other end of the spectrum is an understanding of quantum physics. In this analogy, the water system is showing only the flow of charges (you can think of them as electrons). Water pressure is analogous to total electric potential (voltage), and a pump is analogous to a battery. I've guessed that the top two resistors are in series w/ each other, the bottom two are in series and them 4 resistors are in parallel with the 2 ohms resistor, but that's just a lucky guess. The animation was written by David M. Harrison in April 2003. both pipes, because the amount of water entering one pipe must equal the amount leaving the other.
