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)

Energy is destroyed when it passes through an incandescent bulb.

Answer 1

Fluorescent bulbs are more energy-efficient because they produce light through a different process than incandescent bulbs. In a fluorescent bulb, an electric current passes through a tube containing mercury vapor and phosphor coating. This process produces ultraviolet light, which then causes the phosphor coating to emit visible light. This method requires less energy to produce the same amount of light compared to the heating process used in incandescent bulbs.
