Which makes a bulb glows brighter? Physics Forums

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 …
