Question

Why is tungsten used for making bulb filaments of incandescent lamps?​

Answer 1

$\huge{\underline{\underline {\mathtt{\purple{A}\pink{N}\green{S}\blue{W}\red{E}\orange{R}}}}}$

Because the melting point for tungsten is around 3400 °C (~6200 °F), which is far greater than the actual temperature a bulb actually reaches. This also makes tungsten the metal with the highest melting point.

Answer 2

Answer:

The answer is:

Explanation:

As the melting point for tungsten is high around 3400 °C , which is far greater than the actual temperature a bulb actually reaches.

Tungsten is used for making filament of an electric bulb due to the following reasons:

⦿Being an alloy it has a very high melting point

.

⦿It has very high resistivity so it does not burn easily at room temperature.

⦿The lamp glows at high temperatures.
