Imagine the water flow in your house from the top-up tank in the roof to the cistern in the bathroom. The height difference between the water in the top-up tank and the ball valve in the cistern is the potential that drives the flow of the water. The flow is given by the quantity of water that passes down the pipe
per second and the resistance is the result of the limited size of pipe
that you have to carry the water. These are analogous to the Voltage,
Current and Resistance in an electrical circuit. |
