FAQ

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

👉 Why tungsten filament used in electric bulbs?

Tungsten is used because it has a high melting point and maintains a high strength at high temperatures - like those required to make it hot enough to give off light as a filament in an electric bulb.

👉 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

👉 Tungsten is used for making filament of electric bulbs why?

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

5 other answers

(a) Tungsten is used as filament in electric bulbs. The melting point and resistivity of Tungsten are very high. At high temperatures, it does not burn quite well. The temperature of the electric lamps is extremely high. Hence, tungsten is mainly used as the heating element of electric bulbs.

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

Electric lamps heat up with time as they are used. Since, tungsten has very high melting point, it does not melt even at very high temperatures. Hence, the lamp in not destroyed.

Why is the tungsten used almost exclusively for filament of electric lamps?AnswerTungsten metal is used exclusively for making the filament of electric bulbs because it has a very high melting point.Due to its high melting point, the tungsten filament can be kept white hot without melting away.Other

Tungsten is used exclusively for electric light filaments because it has lowest coefficient of thermal expansion, high melting point and its good tensile strength. Hope this answers your query. With Regards

Why is argon used to fill electric lamps?

Answer. Argon belongs to zero group, i.e., is a noble gas and thus is inert. Hence it will not react with the hot filaments. Hence it is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.

Electric bulb filament?

The filament of an electric bulb is not purely resistive. It contains a very high impedance. By impedance, we know, Z = R + j(X L – X C) As a result, this filament doesn’t only have a resistive quality but also has inductive and capacitive quality. Among these, the resistive quality is very negligible. Resistive nature of filament varies with the variation of power rating of bulb. But it is very less compared to the reactive quality of the electric bulb.

When did lamps become electric?

Sir Humphrey Davy of England invented the first electric carbon arc lamp in 1801. A carbon arc lamp works by hooking two carbon rods to a source of electricity. With the other ends of the rods spaced at the right distance, electrical current will flow through an "arc" of vaporizing carbon creating an intense white light.

When was there electric lamps?

It was Joseph Swan, an inventor from Sunderland, who developed the first practical lamp and led the way in early electrical lighting. Swan supplied arc lamps to light the Picture Gallery at Cragside in Northumberland in 1878, the first house to be lit by electricity, and for Mosely Street in Newcastle, the first electrically lit street in 1879. (1879 was, incidentally the year Edison first demonstrated his own lamp in the USA).
