Tungsten metal is used to make a solenoid type coil an electric bulb
Answers
Answer:
I think the solenoid model of arrangement increases the length of the tungsten filament being used resulting in increase of the resistance of the filament.
This will help in better power generation and better glowing of the bulb.
Hope you will be able to understand.
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.
