WebThe typical cold resistance of a 100 W incandescent lamp is about 9.5 ohms. If that resistance stayed the same with 120 V applied, Ohm's Law tells us that the bulb would draw about 12.5 amps and dissipate about 1,500 watts. That doesn't happen of course, and that's because as the filament heats up, its resistance increases as well. WebApr 7, 2024 · Normal incandescent bulbs use a Tungsten filament and burn at about 2700K. Even if a particular brand has a special filament for a different temperature, that will only slightly shift the relative spectrum.
