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

Compact fluorescent bulbs produce less heat and use less energy because they operate differently from incandescent bulbs. Incandescent bulbs use a filament that heats up to produce light, while compact fluorescent bulbs use electricity to excite mercury vapor, producing UV light that then interacts with a phosphor coating on the inside of the bulb to produce visible light. This process is more energy efficient and produces less heat, making compact fluorescent bulbs an energy-saving alternative to incandescent bulbs.
