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
This is possible due to the difference in the technologies used by compact fluorescent bulbs and incandescent bulbs.
Incandescent bulbs produce light by heating a filament wire inside the bulb until it becomes hot enough to emit light. However, a significant amount of energy is lost in the form of heat, making incandescent bulbs inefficient.
On the other hand, compact fluorescent bulbs use a different method called fluorescence to produce light. Inside the bulb, there is a mixture of gases that emit ultraviolet (UV) light when an electric current is passed through them. The UV light then interacts with a phosphor coating on the inner surface of the bulb, causing it to emit visible light.
This process requires significantly less energy compared to heating a filament, making compact fluorescent bulbs more energy-efficient. They can produce the same amount of light (or sometimes even more) as incandescent bulbs while consuming less electricity. As a result, the homeowners can use compact fluorescent bulbs to achieve the same level of brightness while reducing their energy consumption and electricity bills.
