WebJul 27, 2016 · The light bulb is in series with the wires in the lamp and wall. Since the current through all elements in a series is the same (neglecting capacitance), the elements with higher resistance will dissipate more heat. You want the light bulb to heat up, not your wires in your walls (which can cause fires). It all goes back to the basics: ##P = IV##. WebA lightbulb is labeled "100 watts." What does "100 Watts" represent? the current flowing through the filament when the bulb is on the resistance of the filament the rate of energy being dissipated within the filament of the bulb when the bulb is on the voltage of the battery the bulb should be attached to
