| Jun 23, 2021 at 17:12 | comment | added | Alex | I wasn't able to get the variac that I happened to have at work, to give me a power factor of .5 with an incandescent light. However I managed to get the power-factor with an inverter that we happened to have. | |

I finally got a chance to measure the magnetizing current on my larger variac, and it's only about 16 mA, which implies that the inductance is on the order of 20 H! I really expected the current to be about an order of magnitude larger. | |
