Question

Quizplus · Accepted Answer

The source of electrons that illuminate a common lamp in your home is the atoms in the lamp filament. When the lamp is turned on, the electric current flows through the filament, which causes the atoms to vibrate and release energy in the form of light. The power company, the electrical outlet, the wires leading to the lamp, and the source voltage all play a role in delivering the electricity to the lamp, but they are not the actual source of the electrons that produce the light.
