Electricity and water analogy learning goal.
Electricity and water analogy.
This is sometimes called the principle of continuity.
Switches are like on off shutoff water valves.
For it to be useful one must remain aware of the regions where electricity and water behave very differently.
The analogy here is to water flow or more specific the amount of water flowing through a cross sectional area per unit time.
If you have ever heard of the term ohm that is resistance.
In the water circuit the pressure p drives the water around the closed loop of pipe at a certain volume flowrate f.
Each quantity and each operational relationship in a battery operated dc circuit has a direct analog in the water circuit.
Water analogy to dc circuits.
Electrons can push or pull other distant electrons via their fields while water molecules experience forces only from direct contact with other molecules.
This physics video explains how the electric current flows using the analogy of water flow.
If taken too far the water analogy can create misconceptions.
Think of how fast and how much water is flowing out of your hose.
Fields maxwell equations inductance.
Current law and flowrate for any circuit fluid or electric which has multiple branches and parallel elements the flowrate through any cross section must be the same.
This video is meant for students studying in class 9 and 10 in cb.
This analogy works particularly well because you can imagine the electric meter on the side of your house as measuring the volume of electricity that passes through the meter just as a water meter measures the volume of water that flows in the main pipe to your house.
Electricity can be stored and cycled much like water amps in electronics are like gallons per minute for water systems conductive wire moves electricity similar to how pipes move water.
It s common to hear an analogy which says that electricity is like water it goes something like this.
The nature of the analogies can help develop an understanding of the quantities in basic electric ciruits.
Amps measure current and are like the volume of the flow.
Kw measure power and are like how quickly you fill or empty the bucket.
Kwh measure energy and are like how full the bucket is.
