Electricity And Water Analogy

Amps measure current and are like the volume of the flow.

Electricity and water analogy.

It s common to hear an analogy which says that electricity is like water it goes something like this. 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. Amp or ampere is the unit for current. The analogy here is to water flow or more specific the amount of water flowing through a cross sectional area per unit time.

In the water circuit the pressure p drives the water around the closed loop of pipe at a certain volume flowrate f. Switches are like on off shutoff water valves. The nature of the analogies can help develop an understanding of the quantities in basic electric ciruits. Electrons can push or pull other distant electrons via their fields while water molecules experience forces only from direct contact with other molecules.

Each quantity and each operational relationship in a battery operated dc circuit has a direct analog in the water circuit. This video is meant for students studying in class 9 and 10 in cb. If you have ever heard of the term ohm that is resistance. Electricity and water analogy learning goal.

This physics video explains how the electric current flows using the analogy of water flow. 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. 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. For it to be useful one must remain aware of the regions where electricity and water behave very differently.

Water analogy to dc circuits. This is sometimes called the principle of continuity. If taken too far the water analogy can create misconceptions. Kwh measure energy and are like how full the bucket is.

Volts measure voltage and are like water pressure. Kw measure power and are like how quickly you fill or empty the bucket.
