WebTypically, the resistance of a filament light bulb increases as the potential difference applied rises. While this is true for bulbs with metallic filaments such as tungstenfilament lamps, for other types of bulb, for example carbon-filament lamps, the reverse is true. This is because carbon has a negative temperature coefficient, which means its resistance … Web16 de nov. de 2003 · the resistance higher. If it lights up, it should give a resistance reading, but since you don't know the current, that resistance is not much use to you. I don't have an explanation for your reading.

Higher resistance means light bulb

WebHowever, it is resistance that allows us to use electricity for heat and light. The heat that is generated from electric heaters or the light that we get from light bulbs is due to resistance. In a light bulb, the electricity flowing through the filament, or the tiny wires inside the bulb, cause them to glow white hot.
