Answer:
Explanation:
(i) The electric bulb works on the principle of heating
effect of electric current.
(ii) The intensity of light emitted by the filament of
an electric bulb depends on the temperature of
the filament.
(iii) When electric current is passed through the
filament, a large amount of heat is generated and
filament becomes hot, then emits light.
(iv) The melting point of Tungsten is very high
(3380°C), so that filament can be heated to a high
temperature without melting.
(v) Hence, the filament of electric bulb is made up of
Tungsten.
