Voltage = "Electron Pressure"?

Is it correct to think of Voltage as: "Electron Pressure"? Sebbes333 (talk) 20:00, 7 May 2024 (UTC)[reply]

The talk page is not a question-and-answer forum. However, you can contact me on my talk page to have a brief discussion. There is also reddit ask physics and Quora. Constant314 (talk) 21:12, 7 May 2024 (UTC)[reply]

A simple yes/no answer, or a short clarification would have been a shorter & MUCH more helpful answer, both to Me & to future readers. Sebbes333 (talk) 16:25, 2 June 2024 (UTC)[reply]

In that case, No. Constant314 (talk) 18:00, 2 June 2024 (UTC)[reply]

Perhaps not "electron pressure", but "electrical pressure" is quite appropriate, and in fact you can find voltage often referred to as "pressure" in some sources. Indeed, the concepts of voltage and pressure are very closely related: in a hydrodynamic setting, pressure (in Pa = J/m³) corresponds to voltage (in V = J/C) and volumetric flow rate (in m³/s) corresponds to current (in A = C/s). You can see that the key difference is that in hydrodynamic setting, the "medium" (that on which forces act) is volume (measured in m³), while in the electrical setting, it's charge (measured in C). Observe also that power in electical setting is the product of voltage and current, i.e. V*C = W. In the hydrodynamic setting, power is the product of pressure and flow rate, i.e. Pa * m³/s = W. And there are many more similarities (but also differences, of course); see Hydraulic analogy. 109.81.125.65 (talk) 16:23, 25 May 2025 (UTC)[reply]
