WebbThe 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. Webb7 dec. 2012 · Ohm's law applies and those bulbs are indeed just simple resistive loads. To get the series current, first derive the equivalent resistance at rated voltage and current …
