Visual Electricity Water Analogy

You see amp ratings on just about all electric devices.

Visual electricity water analogy. The electronic hydraulic analogy derisively referred to as the drain pipe theory by oliver lodge is the most widely used analogy for electron fluid in a metal conductor since electric current is invisible and the processes in play in electronics are often difficult to demonstrate the various electronic components are represented by hydraulic equivalents. When describing voltage current and resistance a common analogy is a water tank. Power is the total amount of water flowing in given time. Unlike the water pump in our river analogy however the power plant automatically adjusts to meet the demands of the consumer at the end of the wires.

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. But using water as an analogy offers an easy way to gain a basic understanding. This video is meant for students studying in class 9 and 10 in cb. How can we model the behavior of electricity in a wire with water and a hose.

Voltage is like the pressure that pushes water through the hose. The analogy here is to water pressure. Dc circuit water analogy this is an active graphic. Electricity 101 voltage current and resistance.

Click any part of it for further details. The fundamental laws of electricity are mathematically complex. This physics video explains how the electric current flows using the analogy of water flow. In this analogy charge is represented by the water amount voltage is represented by the water pressure and current is.

If the plant can t keep up with the demands we experience brown outs a shortage of electric power just like water users at the end of a river would run short on water if the pump were too slow. Electricity is basically the set of physical phenomena associated with the presence and motion of electric charge. When beginning to explore the world of electricity and electronics it is vital to start by understanding the. The three most basic components of electricity are voltage current and resistance.

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. The analogy here is to water flow or more specific the amount of water flowing through a cross sectional area per unit time. In general terms charge is water voltage is the pressure of water current is the flow of the water. The water hose analogy for electricity is useful for explaining voltage current and power.

Amp or ampere is the unit for current.
