We all know of wattage ratings for resistors - I'm interested in specs on the
voltage ratings of large resistors. 2 watt carbon resistors and 1 watt
carbon film resistors are rated at 500 volts. I presume that is to limit the
voltage gradient or stress across the resistor so that it doesnt act as a
fuse or firecracker. What about large resistors often used as bleeders on hv
power supplies? I use 200 watt resistors in series and have never had any
problems. I assume they can stand hv due to their long length, about 10"
long, to spread out the voltage gradient. Does anyone have any specs on
their actual voltage rating? 73 Bob W7LR
