Voltage Current Resistance Analogy

So for this analogy remember.

Voltage current resistance analogy. The higher it is the more potential energy the water has by virtue of its distance from the bottom of the falls and the more energy it will possess as it hits the bottom. Just like voltage resistance is a quantity relative between two points. Voltage current and resistance in circuits explained definition animation video for kids voltage current and resistance the relationship between voltage cur. Current is equal to the voltage divided by the.

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. A simple analogy would be to compare a garden hose to a fire hose. For this reason the quantities of voltage and resistance are often stated as being between or across two points in a circuit. 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.

If we draw an analogy to a waterfall the voltage would represent the height of the waterfall. The amount of current in a circuit depends on the amount of voltage and the amount of resistance in the circuit to oppose current flow. The water is there waiting for you to turn on the faucet but. Nothing is coming out of the hose you have screwed onto the faucet.

To model the resistance and the charge velocity of metals perhaps a pipe packed with sponge or a narrow straw filled with syrup would be a better analogy than a large diameter water pipe. We can extend the water analogy to understand resistance too. The garden variety he he has significant pressure voltage and moderate volume amperage capacity and works well in the yard. If we have a water pump that exerts pressure voltage to push water around a circuit through a restriction we can model how the three variables interrelate if the resistance to water flow stays the same and the pump pressure increases the flow rate must also increase.

There is a basic equation in electrical engineering that states how the three terms relate. A neat analogy to help understand these terms is a system of plumbing pipes. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. Ohm s law also makes intuitive sense if you apply it to the water and pipe analogy.

When describing voltage current and resistance a common analogy is a water tank. A basic electrical engineering equation called ohm s law spells out how the three terms relate. Resistance in most electrical conductors is a linear function.
