Maybe it does, like a 3KW kettle uses less energy than a 1.5KW kettle to
boil the same amount of water?

A 3kw kettle does use very slightly less energy - it boils it up
quicker, therefore there is less time for the heat contained within the
kettle to be radiated out to the surrounding air.

On the other hand the higher currents heat up the wires more..;-)

Which might, or might not, be true.

Sadly these things are very much NOT obvious.


Even more sadly, precocious gits who have ticked more than half te boxes
right in a multiple choice O level physics paper, now think that 'know
about physics' well enough to make comments like that.

We've been using an Elitech halogen oven for almost two years now and they
*are* a lot quicker and cook at a lower temperature than an ordinary oven so
they may, in fact, be cheaper to run.
