I bought one of those tiny 650v ballasts they use for miniature flourescent bulbs last year. Frankly, this thing hasn't seen the...light of day ever since ('little joke there, to lighten the mood) and I'd like to give it a nice workout.
Before jumping into things I wanted to apply a few resistive loads and see if I could verify the output is really the 650v, it's advertised to be. Since my multimeter is limited to 250Vrms I figured a voltage divider would be useful but now I need to know if this high voltage may cause any breakdown in the resistors. I'm not in the dark when it comes to resistor basics, but as far as breakdown goes, I don't know watts watts. :lol:
Would a resistor have a bright future dropping such a high voltage, or does the outlook seem dim? I need someone to shed some light on this situation.
(The resistors are 1/4W and/or 1/2W carbon film)
