RE: Power consumption

I have seen the light!!! :-)

220V appliances suddenly look a whole lot more attractive. Thanks Roger, I
get it now. This has been one of those things that's always annoyed me
(like every time the furnace blower motor kicks on) and I've never
understood what was happening. Very cool to have one of the great mysteries
(to me at least) explained.

Thank you,
Mike Benedict

When you apply a load to any power source you get voltage drops in the
wiring
in between the load (in this case a bank of video games) and the power
source
(in this case the transformer out in the back yard). Some of this loss is
resistive, some is inductive. A light bulb running would be an example of a
resistive load, where wiring loses are nice and well defined. So let's
start
with that and my farm shed example.
