Re: Ballast resistor construction

... points (pun intended). My experience: I was testing a 50 KV supply for voltage and current. I have a load I made from a bunch of power resistors ... arcing point so it happened to have some limiting too. Just a note on safety, my load resistor and a HV divider for measuring voltage were well ...
