An incandescent bulb works by using electricity to generate enough heat to make the bulb's filament glow and emit light, while a fluorescent lamp functions by colliding gaseous atoms with electrons and transforming the... More » Science Physics Electricity

The difference between xenon and halogen lights is the gas used in the light bulb. Xenon lamps use xenon gas, while halogen lamps use a gas from the halogen group. Iodine and bromine are the most common halogens used in ... More »

A light bulb glows because of heat that is caused by electricity as it flows through a filament within the bulb. As the wire heat up, it glows as the result of the temperature. More » Science Physics Electricity

An electric light bulb works by conducting an electric current through its wires and the filament once it gets connected to a power supply. As the current flows through the components of an electric bulb, it generates li... More »

Metals conduct electricity well due to the fact that the outermost electrons in their atoms are held by weak atomic forces, allowing these electrons to flow easily from one atom to another. This flow of electrons is what... More »

A tunnel diode works by creating an area of negative resistance for electrons to penetrate the potential barrier of a semiconductor junction. The mechanism of a tunnel diode is based on the principle of quantum mechanica... More »

The most common type of fluorescent light, the hot cathode light, works by using electricity to supercharge the ions of mercury gas encased within a glass tube. When the ions are charged, they emit photons that are conve... More » Science Physics Electricity
