A circuit in a home provides power to a light fixture. The homeowners want to use a compact fluorescent bulb instead of an incandescent bulb. Compact fluorescent bulbs can produce as much light as incandescent bulbs but with less energy. How is this possible?(1 point)

Answer 1

Fluorescent bulbs are more energy-efficient because they produce light by using electricity to excite mercury vapor, which then produces ultraviolet light that interacts with phosphor to create visible light. This process is more efficient than the simple heating of a filament in an incandescent bulb to produce light.
