Shooooot! I actually meant to say the electric potential difference, not just the potential difference. Sorry I thought it was clear since It was posted here.

Back to my original question, do you see now what I meant by it?
Thanks.
It doesn't matter, that was the point of my post. Electrical potential difference is the equivelant of every other form of potential difference by laws of physics.
Work is a force acting upon or displacing an oject.
Work that is driven by electricity is the equivelant of work that is driven by compressed gases, thermal energy, or the gates of Hoover Dam.
Mr. Crutschow described the difference between energy and work.
But the point is, these definitions of work, energy, potential, force, horsepower, pressure, flow, resistance, capacity, etc are pretty universal in their application weather its electronics, mechanics, hydraulics, or pneumatics that we are discussing.
In almost all cases there is an equivelant and the metrics are proportional. In other words, there is an "ohm's law" for pneumatic systems that works the same way as electrical systems, even if the units are not the same.
Even if you look at the RC time constant of a capacitor and the 5 step rise/fall time on a graph, it equates to the response of a compressed air cylinder as it is filled to capacity with a gass through a resistive valve.
I'm off on a tangent, but you see now how these words all have their own meaning and aren't usually interchangeable.
