Hey y'all !!
I recently scored a bunch [ 10 ] 200 ohm, at least 100 watt, 1" dia. 12" long -- ceramic resistors. These have an exposed strip along the side, for an adjustable tap, but there is no indication of how much amperage the coil is good for................The wire, I assume similar to NiChrome is .010 dia. 5 amps would be nice.
I want to rig one with a carbon motor brush as a slider, to make an ersatz rheostat, fed by std. 120v AC to a rectifier bridge, for a light duty DC test bench supply. I have the liberty of burning one up to discover their limit, but would rather not roll that way.
Sound reasonable ??
