Electrical Mechanical Acoustical
voltage force pressure
current velocity vol. velocity
resistor dashpot mesh
inductor mass tube
capacitor spring volume

Why does one circuit seem to be in parallel while the other two are in series?

In an electrical circuit, which is easier to measure: voltage or current?

In a mechanical circuit, which is easier to measure: force or velocity?

Equations converted from TEX to HTML by TTH. I have seen the equations show up properly under Windows using Mozilla 1.7, Firefox 1.0, Netscape 4 & 7, and IE 5 & 6. They do not show up properly for me under Windows using Netscape 6.2, nor under GNU/Linux using Mozilla 1.0.
