Calculating Power Factor

What does the magnetron behave like in a circuit? I realize it's basically
a giant rectifier tube, but I'm not wise on tube characteristics and
behavior. I imagine there's some bizarre resistive component, but that's
all I can come up with.

** Suffice to say that the load presented by a typical microwave oven to the
AC supply is close to sine wave current and pretty much in phase.

Resonance is definitely involved.

I just measured mine to see if an emergency generator would like it.

Measured .95 on a kill a watt.
