Electricity Water Flow Analogy

To understand this better we shall look at the water flow analogy.

Electricity water flow analogy. Index dc circuits. 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. But with some corrections to model calculations can be quite accurate. The water analogy is a fitting introduction.

Water analogy to dc circuits. Imagine that there are two tanks with different amounts of water and the two tanks connected to each other at the bottom with a hose pipe. This physics video explains how the electric current flows using the analogy of water flow. You may click any component or any relationship to explore the the details of the analogy with a dc electric circuit.

But using water as an analogy offers an easy way to gain a basic understanding. Water flowing through pipes is pretty good mechanical system that is a lot like an electrical circuit. The analogy here is to water flow or more specific the amount of water flowing through a cross sectional area per unit time. An electric current is a flow of electrons through a conductor like a copper wire.

The three most basic components of electricity are voltage current and resistance. Electric current flow is proportional to voltage difference according to ohm s law and both the bird s feet are at the same voltage. In the water circuit the pressure p drives the water around the closed loop of pipe at a certain volume flowrate f. Amp or ampere is the unit for current.

The analogy here is to water pressure. If the resistance to flow r is increased then the volume flowrate decreases proportionately. This video is meant for students studying in class 9 and 10 in cb. You see amp ratings on just about all electric devices.

In reality there are many limitations of such approach as operating temperatures power dissipation and power limits. Since we can t see electrons it would be nice to have a model or an analogy of electric circuits to help us understand circuits better. Again this is a common quantity. If charges ever flowed as fast as water can flow in pipes the electric current would be immense and the conductors would become incandescently hot and perhaps vaporize.

Electricity is basically the set of physical phenomena associated with the presence and motion of electric charge. The fundamental laws of electricity are mathematically complex. Voltage is like the pressure that pushes water through the hose. It was used by the physicists at a state s iso independent systems operator that oversaw the reliability of the state s electricity grid to explain how they route electricity to ensure power flows where needed.
