Andy Engel resistor on light switch

Posted by janicholson on October 30, 2005 at 16:42:16 from (66.173.50.34):

To replace the resistor with a substitute' use a wire wound ceramic power resistor of between 2 ohms, and 4 ohms. It should handle 50 watts dissipation. This means it looks like a little finger sized cigar with a terminal on each end. A 2 ohm will be brighter than a 4 ohm. If it is not 50 watt, it will glow and self destruct. (assuming three lights draw 8 amps on high, with the resistor in the circuit they should draw about 5-6 amps. Watts = amps times volts, so 6X6=36 watts. 50>36 and it won't burn up. It will get hot, it is supposed to.
