Here's how:
* Light: The filament in a traditional incandescent bulb heats up due to electrical resistance, causing it to glow and emit light. LED bulbs use semiconductors to create light more efficiently.
* Heat: The filament in incandescent bulbs gets extremely hot, releasing heat as a byproduct. This is why they are often used for heating purposes.
* Sound: While not as prominent, even a standard incandescent bulb can produce a subtle buzzing sound due to the vibration of the filament as it heats up.
Other devices that can transform electrical energy into these forms of energy include:
* Speakers: Electrical signals are converted into sound waves by vibrating a diaphragm.
* Heaters: Electrical resistance causes wires to heat up, providing heat.
* Lasers: Use electrical energy to create a focused beam of light.
