Is it really true that turning on a microwave with nothing in it will

Derp.

It was a sensible question.Â* This could be done by accident.

I interviewed with a place once that was doing something with testing
microwave ovens.Â* They ran them all the time with nothing in them.Â* I had
always read that you should not operate them with nothing to absorb the
energy and mentioned that.Â* I got a strange look from the guy.Â* Obviously
the energy that would be absorbed is within the limits of what the ovens
were designed to get rid of.

It seems nothing happens, well no fire or explosion anyway.Â* He never
said if it still worked afterwards:

Why don't you simply put a load meter on the microwave and try running
it empty or with a cup of water. I expect that with no load the unit
will simply not draw as much current.

Do regular ovens 'care' if something is in them or not? Why should a
microwave?
