Voltage Water Analogy

In electrical engineering there is a basic equation that explains how voltage current and resistance relate.
Voltage water analogy. Charge coulombs is like water volume liters voltage is like water pressure kpa or psi current amps is like water flow rate liters per second. When describing voltage current and resistance a common analogy is a water tank. So for this analogy remember. This model assumes that the water is flowing horizontally so that the force of gravity can be ignored.
This is one i use to explain the difference to my customers imagine your water faucet inteh front yard. As per the water tank analogy water is analogous to charge pressure is analogous to voltage and the flow of water is analogous to current. Voltage is energy per unit charge. Consider the water reservoir analogy.
The water is there waiting for you to turn on the faucet but. The hydraulic analogy while having its limits is a very useful tool for visualizing the operation of electric circuits. Thus voltage is analogous to pressure. In this case electric potential is equivalent to pressure.
There is a basic equation in electrical engineering that states how the three terms relate. V i x r. In this analogy charge is represented by the water amount voltage is represented by the water pressure and current is represented by the water flow. Because voltage is an expression of potential energy representing the possibility or potential for energy release as the electrons move from one level to another it is always referenced between two points.
In general electric potential is equivalent to hydraulic head. This equation written below is known as ohm s law. Dc circuit water analogy this is an active graphic. A neat analogy to help understand these terms is a system of plumbing pipes.
Hydraulic analogy with horizontal water flow voltage current and charge. The flow of water can be analogous to the amperage of current which is the rate of flow of charge. Nothing is coming out of the hose you have screwed onto the faucet. Voltage is represented in equations and schematics by the letter v.
The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. The best analogy is usually the stream of water.
