An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament from oxidation.

Answer 2

• An electric bulb is a device that creates light when electricity is applied to it. 
• The electrical bulb is also known as the light bulb.
• The electrical devices are of various types:-
• Incandescent electric bulb - Electricity is converted to light in incandescent electric bulbs by passing a current through a filament. A thin wire is also known as a filament. Furthermore, electric filaments are primarily made of metal tungsten.
• Fluorescent Light Bulb- Fluorescent light bulbs are very efficient. In addition, they produce only a quarter of the heat produced by an incandescent bulb. Furthermore, in comparison to incandescent bulbs, fluorescent bulbs last longer.
