Quizplus · Accepted Answer

When you turn on the lamp, the electrons in the filament get excited and jump to a higher energy level. As they return to their original energy level, they release energy in the form of light. Therefore, the glowing comes from the same electrons in the filament. The electrons that flow in the circuit to your lamp also contribute to the overall functioning of the lamp but they do not directly produce the glowing.
