Why does an electric light burn even when there is no oxygen in the bulb?

Solution

The term ‘burning’ is not appropriate for an electric light or a lamp. Scientifically speaking, burning process involves combination of a substance with the oxygen element to form oxide. But, an electric light only takes enough electric current to make a piece of metal glow brightly (incandescence) and give out visible light. If there is a tiny crack in the glass of the electric light, the oxygen present in the normal air will quickly make the filament burn away.
