Bulbs

Bulbs are incandescent lamps, which works by incandescence. In a bulb through a thin filament, electric current passes, thus heating it up and then the bulb produces light. A glass bulb encloses the filament and thus prevents oxygen from entering and reaching the heated filament as oxygen causes oxidation leading to rapid destruction of the filament.

Bulbs are also termed as “electric lamps.” According to some the credit of invention of light bulbs goes to Theadore Rellor. However, Edison is noted as the inventor of light bulb.
