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 … See more There is no unique paradigm for establishing this analogy. Different paradigms have different strengths and weaknesses, depending on how and in what ways the intuitive understanding of the source of the … See more EM wave speed (velocity of propagation) is equivalent to the speed of sound in water. When a light switch is flipped, the electric wave travels very quickly through the wires. Charge flow speed (drift velocity) is equivalent to the … See more If taken too far, the water analogy can create misconceptions. Negative transfer can occur when there is a mismatch between phenomena in the source (hydraulics) and the … See more • Animation • Hydraulic Analogy for Inductive Electric Elements [1] See more Voltage, current, and charge In general, electric potential is equivalent to hydraulic head. This model assumes that the water is flowing horizontally, so that the force of gravity can be ignored. In this case, electric potential is equivalent to pressure. … See more If the differential equations are equivalent in form, the dynamics of the systems they describe will be related. The example hydraulic equations approximately describe the … See more • Bond graph • Fluidics • Hydraulic circuit • Hydraulic conductivity See more WebThe water/hose analogy for electricity is useful for explaining voltage, current, and power. In general terms, charge is water, voltage is the pressure of water, current is the flow of the water. Power is the total amount of water flowing in given time.

WebMay 13, 2014 · The earliest electrical concepts used fluid flow as analogous and identical processes. Only after Georg Simon Ohm asserted that current and voltage are linearly related did scientists understand that fluid and electrical properties are similar, but not identical mathematically.

WebCurrent-Flowrate Analogy. Volume flowrate in liters/min, cm 3 /sec, m 3 /sec, etc. Electric current flow in coulombs/sec = amperes. A large pipe offers very little resistance to flow, as shown by Poiseuille's law. A wire offers very little resistance to … Web3 Electric-fluid analogy pH t In the electric-fluid analogy[3], a flow field is modeled as the electric circuit as shown in Fig. 3 by the analogy of basic transient equations between flow field and electric circuit The pressure P and flow rate Q correspond to 1 electric potential difference E and current I, respectively. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/watcir3.html only one foot swollen during pregnancy
