Explain, why the filament of electric lamp is made of tungsten?

Question

Answer

Tungesten has high melting point and high resistivity which are needed for glowing bulb that's why filament of bulb is made up of tungesten.

Answer

It has high melting point, very low rate of oxidation

Answer

Due to it's high melting point

Answer

Tungsten has high melting point and it serves the purpose of lighting the bulb

Answer

Tangent have high melting poing it needed to glowing bulb

Answer

The filament of an electric lamp is made up of tungsten because of the following reasons->
*tungsten have high melting point
tungsten have high boiling point,
tungsten glows on heating

Answer

Becoz tungsten has high melting n boiling point

Answer

Filament of an electric lamp is made of tungsten as it does not easily  at high temperature a bulb is fulled of gases  initrogen and argan to providing the life of filament tungsten has highest melting point 3380'C

Answer

Oh

Answer

Tungsten has a high melting point (

3380

∘

C) and becomes incandescent (i.e., emits light at a high temperature) at 2400 K.

Because of very high melting point tungsten doesn't melt. That's why in bulb or lamps we use tungsten filament.

Answer

Because it has high melting point.

Answer

Because melting point of tungsten is very high.

Answer

It is used for 2 reasons....

1.Due to its high melting point

2.Due to its high resistivity

Answer

Tungsten has high melting point and high resistance. so it is used to prepare filament of electric bulbs. Due to high resistance of tungsten, large quantity of heat is produced due to which the bulb glows and due to its high melting point, it does not melt even at higher temperature.

Answer

Tungsten is a metal with a very high melting point. When even large amount of heat is passed through it, then also it does not melt and starts glowing. Due to this property it is used in making filaments of the bulbs. Also it does not oxidise since nitrogen gas is filled inside the bulb.

Answer

Because tungsten is the only metal having highest melting point and thus would not break so easily due to short circuit or other means.

Hope it helps!

Answer

Because tungsten metal's melting point is  very high .and electric lamp needed high melting point yo glow.that is why filament of a electric bulb is made up of tungsten.
