Electricity is almost always invisible, but we can use something that acts similarly - water - to make the concept understandable. A circuit with a battery - like in the previous graphic - operates at a certain voltage and current, similarly a basic system used to transport and store water operates with a certain pressure and volume.
- The voltage an electrical circuit is similar to the pressure in a water system.
- The current an electrical circuit is similar to the flow in a water system.
- The wires and load in an electrical circuit create resistance. The pipes and devices that consume water, like a sprinkler, also create friction.
