Question

An electric filament lamp with a clear glass bulb when switched on gives a bright white light. The bulb contains a small quantity of argon gas. Briefly describe the parts played by conduction convection and radiation in the loss of heat from the lamp filament.

Answer 1

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. Current is supplied to the filament by terminals or wires embedded in the glass. A bulb socket provides mechanical support and electrical connections.
