Setup: transformer, single rectifier in series with a load resistor.
Will the power company still bill me for the half of the cycle where no power is drawn by the load resistor?

The power company bills by the amount of power you take from them. Review Volts times Amps and take a look at "power factor " while you are at it and then get back.

** Fact is there will not be any missing half cycles in the primary current of the transformer - and the current draw wave will be far from sine or symmetrical.
Also, the iron core may become so magnetised by this that large current peaks occur in the primary producing lots of causing "I squared R " ating - and YOU have to pay for that !!

Suppose I put a single (large) rectifier in series with a resistive load, say an electric heater for example, across the the two 230 legs of my 115/230 volt supply? What then? Successive half waves of current? Power consumed =3D half? Effect on utility electric meter?
Heater is half as hot.
Yes.
Yes.
It reads half.
