Voltage Current Resistance Analogy

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size.

Voltage current resistance analogy. For this reason the quantities of voltage and resistance are often stated as being between or across two points in a circuit. We can extend the water analogy to understand resistance too. Just like voltage resistance is a quantity relative between two points. 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.

By comparing equation 4 and equation 6 we will get the analogous quantities of rotational mechanical system. Current is equal to the voltage divided by the. The mountain analogy in this article will help you to understand these properties. 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.

Similarly there is a torque current analogy for rotational mechanical systems. There is a basic equation in electrical engineering that states how the three terms relate. 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.

Resistance in most electrical conductors is a linear function. 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. The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. When describing voltage current and resistance a common analogy is a water tank.

If we draw an analogy to a waterfall the voltage would represent the height of the waterfall. 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. Current voltage resistance and power are the four basic properties of electrical circuits. Let us now discuss this analogy.

Ohm s law also makes intuitive sense if you apply it to the water and pipe analogy. So for this analogy remember. A fire hose hooked directly to a hydrant has lots. A neat analogy to help understand these terms is a system of plumbing pipes.

A simple analogy would be to compare a garden hose to a fire hose.
