Does not support combustion.<\/p>\n<p>Nitrogen is used in electric bulbs because it does not support combustion. This means that it will not react with the filament in the bulb, which is what produces the light. If a different gas were used, it could react with the filament and cause it to burn out more quickly.<\/p>\n<p>Option A is incorrect because nitrogen is not lighter than air. In fact, it is slightly heavier than air.<\/p>\n<p>Option B is incorrect because nitrogen does not produce more light in the bulb.
