The energy dissipated in a light bulb in a circuit is provided by the
A)lamp filament itself.
B)wires leading to the lamp.
C)voltage source.
D)none of the above

Question

Quizplus · Accepted Answer

The energy dissipated in a light bulb is given by the voltage source of the circuit, which creates an electric field that forces the charged particles in the circuit to move through the bulb's filament, where they collide with atoms and give off energy in the form of heat and light. Therefore, the correct choice is C, as the energy is not provided by the bulb filament itself or the wires leading to the lamp.
