Top best answers to the question «Why is tungsten used for the filament in electric bulb»

The metal tungsten is almost exclusively used for the filament of the electric lamp because it has a very high melting point due to which it does not melt even when it is heated to high temperatures due to the passage of electric current.

FAQ

Those who are looking for an answer to the question «Why is tungsten used for the filament in electric bulb?» often ask the following questions:

👉 Why is tungsten used for filament of electric bulb?

The main reasons why tungsten is used in light bulbs is because it has a high melting point, high electrical resistivity and is far more durable than any other available option. These properties make it suitable since the filament

👉 Why tungsten is used for making filament of electric bulb?

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

👉 Why filament of electric bulb is made of tungsten?

Melting Point of filament is very high. The resistance of filament should be high so that it can produce heat and light and its melting point should also be high so that it does not melt at the high temperature at which it is producing light. Answer- (A)

Who invented the electric filament?

We all learned in our history classes that Thomas Edison invented the light bulb in 1879 and that the first successful filament was a carbonized piece of cotton thread that burned for 13.5 hours. Today, light bulb filaments are not something we think about, unless they burn out, but their early development is a fascinating story of 19 th century chemistry and materials science.
