An electric current can be compared to a pipe or hose ...
The pressure inside the hose is like voltage (V). The rate of discharge, or flow, is like current intensity or amperage (A). The friction along the inner wall of the hose is similar to resistance (Ω). Power (W) is what's produced by multiplying pressure by the available flow. And the amount of water used over a given period of time is like energy consumption (Wh or watthour).
