Incandescent Bulb Has Resistance at Darcy Sunderland blog

Incandescent Bulb Has Resistance. Use ohms law to work back from the wattage and the voltage. Also note the actual filament resistance is different between when it. How does resistance affect the brightness of an incandescent light bulb? The typical cold resistance of a 100 w incandescent lamp is about 9.5 ohms. An increase in current means. The wattage rating on the bulbs is given by looking at the power (which can be heat or light) generated by. The filament in an incandescent bulb does not have a constant resistance. If you take a bulb and increase the voltage across it, the current increases too. The resistance of an incandescent light bulb. Generally it is the resistance of the bulbs thats actually constant. 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. Yet the filament is actually made of several feet of very thin wire cleverly coiled to. A lightbulb (a plain old incandescent lamp) is typically brought up as an example of resistive load.
