Voltage Pressure Analogy

A pump takes in water at low pressure and does work on it ejecting it at high pressure.

Voltage pressure analogy. A neat analogy to help understand these terms is a system of plumbing pipes. A battery takes in charge at low voltage does work on it and ejects it at high voltage. Related questions to study. In the impedance analogy the ratio of the power conjugate variables is always a quantity analogous to electrical impedance.

Both are two terminal devices. Voltage and pressure are measured with voltmeters and pressure gauges respectively. Let us now discuss about this analogy. Neither valve in figure 5 will do a safe and effective job of stopping the motor.

Prev question next question. The garden variety he he has significant pressure voltage and moderate volume amperage capacity and works well in the yard. A simple analogy would be to compare a garden hose to a fire hose. A battery is analogous to a pump in a water circuit.

A fire hose hooked directly to a hydrant has lots. 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. So for this analogy remember. A battery takes in charge at low voltage does work on it and ejects it at high voltage.

There is a basic equation in electrical engineering that states how the three terms relate. Another variation is required for acoustical systems. When describing voltage current and resistance a common analogy is a water tank. For instance force velocity is mechanical impedance.

The voltage is equivalent to the water pressure the current is equivalent to the flow rate and the resistance is like the pipe size. Here pressure and voltage are made analogous impedance analogy. Voltage is represented in equations and schematics by the letter v. The point is a one for one analogy between the electrical and hydraulic circuits creates problems in the hydraulic circuit.

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. A pump takes in water at low pressure and does work on it ejecting it at high pressure. A battery is analogous to a pump in a water circuit. Thus voltage is analogous to pressure.

As per the water tank analogy water is analogous to charge pressure is analogous to voltage and the flow of water is analogous to current.
