the reason that tungsten is better then carbon for light filaments is because the melting point is higher,. the melting point of carbon is only 3550, as where tungstens melting point is 3695

Tungsten has a high melting point of 3422°C, which allows it to withstand the high temperatures produced when an electric current passes through the filament, without melting. This property helps the filament to emit light efficiently and have a longer lifespan.

Which element is used in the filaments in incandescent lamps?
Tungsten is commonly used in the filaments of incandescent lamps because it has a high melting point and does not easily evaporate at high temperatures, making it suitable for prolonged use as a source of light.
Who invented the tungsten filament lamps?
Thomas Edison is credited with inventing the tungsten filament lamp in 1879. Edison's improved design used a carbonized bamboo filament that was later replaced with tungsten due to its durability and higher melting point.
What is the Most suitable for making an electromagnet. a.copper b.iron c.lead d.tungsten?
b. Iron is the most suitable material for making an electromagnet due to its high magnetic permeability and ability to retain magnetization. Copper, lead, and tungsten are not as effective in creating a strong magnetic field.
Is tungsten a metal or a non metal?
Tungsten is a metal. It is a transition metal with the highest melting point of any element, making it a valuable material for applications that require high temperature resistance, such as in light bulb filaments and aerospace components.
What are some of the components in a light bulb?
A light bulb typically consists of a filament, which produces the light when electricity passes through it, and a glass bulb enclosing the filament to protect it from damage and to contain the inert gas (such as argon or nitrogen) that helps prevent the filament from burning. The bulb also has a base that connects the light bulb to the electrical circuit.
Suggest the physical property that can render tungsten suitable for making filament of tungsten light bulb?
The high melting point of tungsten (3422°C) is the physical property that makes it suitable for making filaments in tungsten light bulbs. This property allows the filament to reach high temperatures without melting, resulting in the efficient emission of light.
Why is tungsten suitable for making filament of a bulb?
Tungsten is suitable for making a filament in a light bulb because it has a very high melting point, allowing it to operate at high temperatures without melting. It also has a low vapor pressure at high temperatures, which helps the filament last longer without evaporating. Additionally, tungsten is a good conductor of electricity, making it efficient at converting electrical energy into light.
What elements are in light bulbs as a filament?
The filament in incandescent light bulbs is typically made of tungsten. Tungsten has a high melting point and is a good conductor of electricity, making it suitable for use in light bulbs.
Which metal is used in making filament of a bulb?
The metal is Tungsten.
Why the filament of a bulb is made of tungsten but not of copper?
Because when heated, copper would react with the oxygen in the air and oxidise. Tungsten is not as reactive (I think, but check). I think Argon can also be used as a light bulb filament. Tungsten has a higher melting point than all other metals (3422 degrees C) and a very low coefficient of expansion, making it suitable for the filament in incandescent light bulbs. Argon is an inert gas used in incandescent bulbs to prevent chemical reactions which might degrade the filament.
Which elements is used in light bulbs as a filament?
Tungsten ( chemical name Wolfram ) is used for the filament of an incandescent lamp. This is due to ability for making fine guage Tungsten wires , mechanical strength of such wires and the High melting point , which is considerably more than the normal operating temperature of the filament.
Which elements are used to make a filament?
The most common element used in making filaments is Tungsten.
Why tungsten filament bulb is preferred in stefan's law experiment?
Tungsten filament bulbs are preferred in Stefan's law experiments because they can reach high temperatures without melting, allowing for accurate measurements of the bulb’s temperature. The filament emits a continuous spectrum of light, which is essential for accurately measuring the radiation emitted by a blackbody. Additionally, tungsten has a high melting point, making it suitable for use in high-temperature environments during the experiment.
What metal is a light bulb filament made of?
A light bulb filament is typically made of tungsten metal. Tungsten is chosen for its high melting point and good electrical conductivity, making it ideal for producing light through resistive heating when an electric current passes through it.
Which element is used in the filaments in incandescent lamps?
Tungsten is commonly used in the filaments of incandescent lamps because it has a high melting point and does not easily evaporate at high temperatures, making it suitable for prolonged use as a source of light.
Who invented the tungsten filament lamps?
Thomas Edison is credited with inventing the tungsten filament lamp in 1879. Edison's improved design used a carbonized bamboo filament that was later replaced with tungsten due to its durability and higher melting point.
What is the function of the Tungsten filament in a light bulb?
Because it has a very very high melting temperature: 6191F, 3422C. However it is also very difficult to work with, so early light bulbs used carbon for making the filament instead. Around the year 1900, carbon filaments were replaced with tantalum filaments. It was not until about 1910 that it became practical to make tungsten filaments.
