Zelphie, Ω's law applies to all electrical circuits, no matter what nature. And power is always related to Ω's law, (I^2*R, V^2/R)
Stota, the only (solid) vaporizers I'm familiar with... I am not allowed speaking about. You may have trouble reaching the temperatures required to vaporize from solid material, and you might have trouble finding a device that will allow you to press the button long enough to get a decent "puff". Also, what you call "wax" will completely clog the atomizer with resin residue.
Sorry to burst your bubble, but anyhow, you will have realized by now that we only deal with ejuice here - no solids.
