How does the resistance of a filament lamp change when the current is increased?

Answers

Answered by tarunreddy83pbchil

This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases. Thecurrent flowing through a filament lamp is not directly proportional to the voltage across it.
