Current Analog-water flow.gif

Description:

A large jug filled with water is drained by two tubes. One has a significantly larger diameter than the other. The pressure (analogous to electric potential) is the same for both tubes. The larger diameter tube allows more water to flow (small resistance) than the small diameter tube (large resistance).
