What is the glow of a battery?
As early as 1800 alexander Volta in an experiment had observed a copper wire glow when it was connected between the two terminals of the battery. The glowing produced light and man has been in need of light, there was hope for a solution. Two years later Humphry Davy would experiment with a charcoal electrode and when connected with battery electricity it glowed. Carbon rod and platinum filament were noted to glow but the challenge was that they burned out after a few hours. In 1879 Thomas Edison experimented the glowing with carbon filament which had a better result and longer life. However, it is 1904 that tungsten filament was produced, the metal with the highest melting point known had a long life before it could burn. To increase the lifetime, the filament was housed in clear glass with neutral gases or vacuum, this was to limit oxygen that accelerated burning.
