I want to use a MOT (microwave oven transformer) for something it's not intended for. As a consequence, I need to limit the current so it doesn't melt itself. I am planning on connecting the ballast to the primary. The load on the secondary should be capacitive. I understand that a resistive ballast will limit current because
V=I•R, so if V is constant,
I will be relatively constant.
How does a reactive ballast limit current? Can I use a capacitor instead of the usual inductor? If I use both (in series) to correct the power factor, will that counteract the ballasting? Will connecting two MOTs, primaries in parallel, secondaries in series, change much?
