Question

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

Answer 1

Answer:

bcz

Explanation:

bcz tungsten has a very high melting point and shines in vaccum or nitrogen gas

Answer 2

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.
