AC and DC: Electrically speaking

Some idle musing on the train ride in this morning led me to the conclusion that the terms AC and DC are misnomers.

We are taught they they stand for Alternating Current and Direct Current, but when they show graphical representations of said currents they show the voltage waveforms. AC normally shows a nice sine wave, while DC's voltage is at a constant level.

Being you can't have negative current; though it may change direction, the terms should be AV: Alternating Voltage and CV: Constant Voltage. I feel that this more accurately describes what is happening. So that U.S. standard home power would be 120AV and a power supply to a IC board would be labeled as +5CV

I know that I won't change 150+ years of electrical teaching and dogma, but this is what I think of these terms.

Thoughts?

This time a giant lion head. :=3

I used mostly wool, except for marble for the canine, smooth sandstone for the muzzle area and the white under the eye, and oak planking for the shadowed areas.

As with the Amtrak arrow it was done in Creative mode.
