WebbWhen current is flowing through the light bulb, the resistance of the filament causes a loss of voltage that is proportional to the resistance and the amount of current. We refer to this as the voltage across the bulb or as the bulb’s voltage drop. Figure 4. Voltmeters are used to measure the voltage across the light bulbs. WebbA traditional light bulb has a thin metal filament. When there is an electric current in it, it gets so hot that it glows. But this is not a very efficient way of lighting a building – most of the power is radiated as invisible infrared radiation rather than useful visible light.
