FAQ

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

👉 Which metal is used in filament of electric bulb?

Tungsten is the metal which is used as a filament in an electric bulb. As tungsten has high melting point due which it does not get melt when operated for long time and there is no effect of heat on the bulb.

👉 Which metal is used to make the filament of an electric bulb?

Name the metal which is used to make the filament of an electric bulb. - 20323591

👉 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.

Tungsten filament is used in electric bulb since melting point of tungsten is very high. Also resistivity of tungsten is high.

To get white light you need the filament to reach 2700-3300K to give off white yellow light. The reason tungsten is used is because it has the highest melting temperature of any element at 3600K. For a typical incandescent light bulb, the Tungsten filament operates at approximately 2500 Celsius. Hence, the filaments are made of tungsten.

Incandescent bulbs typically use a tungsten filament because of tungsten’s high melting point. A tungsten filament inside a light bulb can reach temperatures as high as 4,500 degrees Fahrenheit. A glass enclosure, the glass “bulb”, prevents oxygen in the air from reaching the hot filament.

So this is your junior high science homework? Modern bulbs have no filament, they are almost all LEDs. You might find some CFLs but they contain mercury so are pretty rare these days. Before LEDs, and before CFLs, we used Tungsten Filament Lamps, ...

Assertion:- Tungsten filament is used in electric bulbs.
Reason:- Tungsten is a metal of high melting point. 14626764. 3.0k+. 60.0k+. 2:02. An electric bulb of 100 watt is connected to a supply of electricity of 220 V . Resistance of the filament is. 15944803. 1.3k+.

The metal filament gradually shortened in use; the filaments were installed with large slack loops. Lamps used for several hundred hours became quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913…

This bulb makes use of a tungsten filament which is the main light producing component in the bulb. There are a few reasons as to why this became the material of choice for these bulbs. 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.

The filament used in an electric bulb has to get heated up to a very high temperature in order to emit light. if a filament of low melting point is used it will melt and the bulb will become useless. therefore wires of high melting points are preferred. tungsten has a very high melting point, therefore, it is used as a filament in the electric ...

Answer: This wire is called a filament. The filament is the part of the light bulb that produces light. Filaments in incandescent light bulbs are made of tungsten. When electric current goes through the filament, the filament glows. 1jaiz4 and 40 more users found this answer helpful. heart outlined.

Tungsten is the metal which is used as a filament in an electric bulb. As tungsten has high melting point due which it does not get melt when operated for long time and there is no effect of heat on the bulb.

Tungsten. (i) filament of an electric bulb: When choosing a material for a particular application, many different properties of materials must all be considered together (such as: melting point (MP), boiling point (BP), thermal conductivity, electrical resistivity, cost, etc.).

In an incandescent type of bulb, an electric current is passed through a thin metal filament, heating the filament until it glows and produces light. Incandescent bulbs typically use a tungsten filament because of tungsten’s high melting point. Why are incandescent light bulbs bad? Incandescent bulbs are very inefficient energy consumers.

answered Sep 11, 2018 by SunilJakhar (89.1k points) selected Sep 12, 2018 by faiz. Best answer. (i) A wire made of tungsten is used for filament of electric bulb because it has a high melting point and high resistivity.

tungsten has a very high melting point, therefore, it is used as a filament in the electric bulb.

Incandescent electric bulb- These bulbs turn electricity into light by sending the electric current through filament. Furthermore, filament refers to a thin wire. Moreover, electric filaments comprise mostly of the metal tungsten. Most noteworthy, it is the resistance of the filament which actually heats the bulb up.
