I guess you could say the current is doing the work as its the amount of actual electrons passing a point in given (1 coulomb per second). Where as voltage is the force behind the electrons. |
Michael, I’m in complete agreement with your observation that voltage and current are interconnected / inseparable.
The point I was trying to make is; as electronics people and more to the point, DAW screen viewers, it is easy to get focused on voltage. But signals are 3 dimensional. They contain voltage, current and time.
Ref the original question; RMS is a measure of two of these dimensions, voltage and time. The formula for RMS is the same as used to calculate the surface area of an irregular two dimensional shape.
There is more to sound then what you see on the screen.
