Incandescent Light Bulb Resistance at Krystal Terry blog

Incandescent Light Bulb Resistance. The filament in an incandescent bulb does not have a constant resistance. Metals that let electricity flow easily are good conductors that have low electrical resistance; The resistance of an incandescent light bulb determines the amount of electrical current flowing through the filament. That's what the math says: Use ohms law to work back from the wattage and the voltage. Also note the actual filament resistance is different between when it. The typical cold resistance of a 100 w incandescent lamp is about 9.5 ohms. What confuses me, is that apparently for an incandescent light bulb, less resistance=more heat? 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. Electricity flows better through some materials than others. A lightbulb (a plain old incandescent lamp) is typically brought up as an example of resistive load. An increase in current means. If you take a bulb and increase the voltage across it, the current increases too. That doesn't happen of course, and that's because as the filament heats up, its resistance increases as well. Yet the filament is actually made of several feet of very thin wire cleverly coiled to.
