Incandescent Light

Incandescent light explained in an easy to understand way:

Imagine trying to get warm by wrapping yourself in a cozy blanket on a chilly night. Just like your body generates heat and transfers it to the blanket, causing it to warm up and provide comfort, an incandescent light bulb works by passing an electric current through a metal filament, heating it until it glows and emits light. The connection is that both scenarios involve applying energy to a material—your body to the blanket, and electricity to the filament—to produce a desired effect: warmth in one case and light in the other.
