Tungsten is used to make a solenoid type coil in an electric bulb.

Text Solution

Verified by Experts

(1) The intensity of light emitted by the filament of a bulb depends on the temperature of the filament. It increases with the temperature.
(2) The melting point of the material used to make the filament of a bulb should be very high so that the filament can be heated to a high temperature by passing a current through it, without melting it. This enables us to obtain more light. The melting point of tungsten is very high `(3410^(@)C)`. Hence, tungsten is used to make a solenoid type coil (filament) in an electric bulb.
