The science and controversy behind your lightbulbs

Light bulbs have a very simple structure. At the base, they have two metal contacts, which connect to the ends of an electrical circuit.

The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied ...

Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. Let There Be Light · Down the Tubes · Cooking with Gas · Start it Up

A lightbulb's glass envelope is designed to keep water vapor and oxygen away from the filament, which would otherwise oxidize the metal within seconds.

Light bulbs (at least the incandescent kind) glow by taking the little piece of metal inside the bulb (called the filament) and heating it up a whole lot. You ...

Essentially, the lightbulb is a very thin filament of hard-to-melt metal – tungsten, usually – encased in a glass bulb filled with inert gases so that the filament doesn't oxidise and disintegrate. The electricity causes the wire to glow and a portion

An incandescent light bulb operates by passing an electric current through the thin tungsten filament housed within a glass bulb.

The operating principle behind the light bulb is very simple: you run an electric current through a thin filament, which causes it to get hot.

Fluorescent bulbs use the principle of fluorescence, where the mercury vapor is energized using the electric current flowing through the bulb.
