What Is The Resistance Of An Incandescent Light Bulb at Cody Maria blog

What Is The Resistance Of An Incandescent Light Bulb. Is it good enough to assume a linear relationship and therefore use ohm's law, v=ir, as the basis for finding the resistance? Or is there a better way to do this? When the bulb is glowing, the resistance (the slope of the curve) is around 490 ω. For materials (like this filament made of tungsten), the resistance is proportional to the temperature. The wattage rating on the bulbs is given by looking at the power (which can be heat or light) generated by. The resistance of an incandescent light bulb determines the amount of electrical current flowing through the filament. The resistance of a light bulb changes with the temperature of the filament in the bulb, and therefore changes with the voltage. Also note the actual filament resistance is different between when it. Use ohms law to work back from the wattage and the voltage. Yet the filament is actually made of several feet of very thin wire cleverly coiled to. Generally it is the resistance of the bulbs thats actually constant. A lightbulb (a plain old incandescent lamp) is typically brought up as an example of resistive load.
