How can you determine the wattage rating of small color coded resistors?
allow a generous margin of ignorance.
No, just cooled the way the manufacturers state.I recently bought a 100 watt resistor. It is rated for a whopping 2.7 watts in free air. To actually dissipate 100 watts, looks like it would need to be submerged in liquid nitrogen!
