Voltage can be thought of as the pressure that pushes current through a resistance. It takes 1 volt to push 1 ampere of current through 1 ohm of resistance -- Ohms law.
Resistance should not be thought of as being equivalent to efficiency.
The above is true for Direct Current (DC). AC gets more complicated as power factor comes into play.

I tried to bait ol' Chas down this path last month. But that fox was just too sly (see my post below). Now, with Al, I'm not so sure....
