It just dawned on me that "current" is exactly like the flow of water in a river, also called "current." It's already a flow of charge.

- wbeaty 11y agoAn electric circuit is a circular channel full of water, a loop-river. An off-switch is a wall of dirt placed across the channel. A battery is a dam with a pump, where the pump runs just enough to maintain a 1-ft level-difference across the dam. A resistor is a narrow section in the river, where the rushing water moves fast enough to heat up. (Or maybe a resistor is a swamp full of cattails and mangroves, causing the entire length of river-loop to move slow.) Amperes is gallons-per-second. Voltage is water surface altitude measured with respect to the center of the Earth, or WRT some average water level, or WRT any chosen reference-altitude.
