2500 ohms * 0.1 amp squared = 25 watts

I can’t really read the picture on ebay clear, but it is either 300 volts or 500 volts. I can read .10 AMP clearly

I’m assuming a pretty hefty wattage?

How much each plus shipping?

Recently, there was a brief discussion of having variable resistors in the loop, to tweak the loop current.  With that in  mind, today I came across a box of brand new rheostats marked 2500ohms, 0.1amps. They have screwdriver adjust shafts.  Anyone want some of these?
