What happens to the filament in an incandescent bulb when electrons flow through it?

When electrons flow through the filament in an incandescent bulb, the filament experiences resistance, which leads to an increase in temperature. As the temperature rises, the filament, typically made of tungsten, heats up to a point where it begins to emit visible light. This phenomenon is known as incandescence. The process is fundamentally linked to the conversion of electric energy into thermal energy, which then is emitted as light. The glowing is a direct result of the high temperatures that the filament reaches, which can exceed 2,000 degrees Celsius, making it capable of producing light that we can see. Thus, the correct understanding here is that the thermal energy caused by the resistance to the flow of current is what results in the filament getting hot enough to emit light.
