Voltage And Current Water Analogy

Current is proportional to the diameter of the pipe or the amount of water flowing at that pressure.

Voltage and current water analogy. This video is meant for students studying in class 9 and 10 in cb. In electrical engineering there is a basic equation that explains how voltage current and resistance relate. The water is there waiting for you to turn on the faucet but. This is one i use to explain the difference to my customers imagine your water faucet inteh front yard.

This equation written below is known as ohm s law. This physics video explains how the electric current flows using the analogy of water flow. A resistor would be a reduced diameter. Hydraulic analogy with horizontal water flow voltage current and charge.

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. In the water flow analogy sometimes used to explain electric circuits by comparing them with water filled pipes voltage difference in electric potential is likened to difference in water pressure. V i x r. In this analogy voltage is equivalent to water pressure current is equivalent to flow rate and resistance is equivalent to pipe size.

Voltage chemical reactions radiant energy and the influence of magnetism on conductors are a few ways in which voltage may be produced. Upon completion of this lab a student should be able to. Flow rate models current and water pressure models voltage describe the limitations of the water analogy to electric circuits. Interestingly enough the analogy of a mass potentially dropping from one height to another is such an apt model that voltage between two points is sometimes called a voltage drop.

So for this analogy remember. In a direct current dc electrical circuit the voltage v in volts is an expression of the available energy per unit charge which drives the electric current i in amperes around a closed circuit. A neat analogy to help understand these terms is a system of plumbing pipes. Identify the electrical analogs to the water circuit components e g.

Teacher section water analogy to electric circuits behavioral objectives. In this case electric potential is equivalent to pressure. 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. When describing voltage current and resistance a common analogy is a water tank.

Consider a water tank at a. Nothing is coming out of the hose you have screwed onto the faucet. This model assumes that the water is flowing horizontally so that the force of gravity can be ignored. Click any part of it for further details.
