Explain how light bulbs create light.

Question

(1 point)
Electricity flows through a conductor
• that absorbs heat and turns the heat into light energy.
Electricity flows through an insulator that absorbs electrical energy, transfers it to the light bulb, and converts it to heat and light.
Electricity flows through a conductor that transfers the energy to the light bullb and the light bulb converts it to heat and light.
Electricity flows through a voltage
•that converts electrical energy into light.

Answer 1

Light bulbs create light through the following process: Electricity flows through a conductor, typically a filament in incandescent bulbs or a gas in fluorescent bulbs. In the case of incandescent bulbs, the electricity heats the filament until it glows, producing light. In fluorescent bulbs, electricity excites gas molecules, which then produce ultraviolet light that is converted to visible light by a phosphor coating inside the bulb. Therefore, the correct explanation is that "Electricity flows through a conductor that transfers the energy to the light bulb and the light bulb converts it to heat and light."
