Electricity And Water Analogy

If taken too far the water analogy can create misconceptions.

Electricity and water analogy.

Water analogy to dc circuits. The nature of the analogies can help develop an understanding of the quantities in basic electric ciruits. To understand the analogy between water pressure water flow voltage and current as suggested by the fact that we call both currents the flow of charged particles through an electrical circuit is analogous in some ways to the flow of water through a pipe. 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. This video is meant for students studying in class 9 and 10 in cb. 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. Electrons can push or pull other distant electrons via their fields while water molecules experience forces only from direct contact with other molecules.

Amp or ampere is the unit for current. Switches are like on off shutoff water valves. Amps measure current and are like the volume of the flow. If you have ever heard of the term ohm that is resistance.

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. Fields maxwell equations inductance. This is sometimes called the principle of continuity. Volts measure voltage and are like water pressure.

Think of how fast and how much water is flowing out of your hose. Electricity and water analogy learning goal. 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.

It s common to hear an analogy which says that electricity is like water it goes something like this. Each quantity and each operational relationship in a battery operated dc circuit has a direct analog in the water circuit.
