A glowing filament will be (3) at the high temperature
How does a filament glow?
- When electricity runs through a filament, resistance is produced by the filament to oppose the electricity.
- This resistance in turn turns the electrical energy into heat energy which heats the filament.
- It is due to this heat that is produced that the filament starts to glow.
- Hence, for a filament to glow, high temperature is needed.
Thus, the correct option is (3) at the high temperature.
