Question
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?
Incandescent bulbs produce other forms of energy, too, including heat.
Fluorescent bulbs produce other forms of energy, too, including heat.
Energy is destroyed when it passes through an incandescent bulb.
Fluorescent bulbs have been designed to put out more energy than they receive.
