Question

Give Scientific reasons.
a. Tungsten metal is used to make a
solenoid type coil in an electric bulb.​

Answer 1

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Tungsten is used in electric bulb because Tungsten has a higher resistance and also . have a very high melting point . So , it doesn't melt easily even if we paas high voltage current . the very thin filament of bulb is made up of this metal.

Answer 2

Answer:

Equipments like electric bulbs make use of the heating effect of the electric current. Electrical conductors having higher resistivity are used here. Hence, Tungsten metal is used to make a solenoid type coil in an electric bulb as it has high resistance and high melting point. The light bulb glows when high current is passed through it. Due to the current, this

wire gets heated (to nearly 3400°C) and emits light. The hot wire also radiates heat to a certain extent.
