#Exposition Imagine little particles called electrons. These contain a negative elementary charge. Now imagine water molecules. While water molecules do not carry a charge. Water systems can be used to model the same interaction as an electrical system.
| Water System Term | Electrical System | Note |
|---|---|---|
| Water Pressure | Voltage (V) | Pressure is a measure of how concentrated a force is over an area. |
| Voltage is the electrical potential (think height) of a positive charge. | ||
| Flow Rate | Current (Amperes,A) | The amount of water/electrons moving per second. |
| Pipe Diameter | Wire gauge/Resistance | Wider is easier flow; Narrow is more resistant. |
| Amount | Charge (Coulombs) | Total quantity of water / electron |
| Turbine | Load / Resistor | Uses the energy to do work or control flow by converting to heat |
| Tank | Capacitor | Offers temporary storage |
| Water Hammer | Voltage spike/ Inductance | Sudden changes to flow causes surges |
