What is the wire in a light bulb?
The wire in a light bulb is typically made of tungsten. When an electric current passes through the wire, it heats up and emits light, creating illumination in the bulb. The tungsten wire has a high melting point, allowing it to withstand the heat generated during operation.
Can you use a copper wire to make a filament of an electric bulb?
No, copper wire cannot be used to make the filament of an electric bulb as copper wire has very low resistance. Therefore, the bulb will not glow if current is passed. It would also melt - the filament has to be white-hot to be any use!
What wire gives of light in a bulb?
Typically, a tungsten filament wire is used in light bulbs to produce light when an electric current passes through it. The wire heats up and produces light due to the resistance of the material.
What element are used in light bulbs as a filaments?
Tungsten is commonly used as a filament in light bulbs due to its high melting point and resistance to heat. It can be shaped into a thin wire that glows when an electric current passes through it, producing light.
What is the name of a coiled wire on top of a light bulb that gets heat when energy is turned on?
The coiled wire on top of a light bulb that gets hot when electricity passes through it is called a filament. It is typically made of tungsten, which has a high melting point and can withstand the high temperatures generated by the electric current.
Is copper wire the same as thugsten wire?
No. Copper wire is made of the element copper. Tungsten wire is made of the element tungsten. Copper wire is made to conduct electricity. Tungsten wire is made for the filament in light bulbs as tungsten does not melt under even very high temperatures.
What elements would be expected to best conduct heat and electricity?
Metals conduct heat and electricity best. Among metals the softer (less dense) metals such as aluminum, copper, silver, etc. We use copper wire to deliver electricity to an incandescent light but tungsten for the filament. Other things affect the heating effect, but the resistance of the tungsten.
What is the wire in a light bulb?
The wire in a light bulb is typically made of tungsten. When an electric current passes through the wire, it heats up and emits light, creating illumination in the bulb. The tungsten wire has a high melting point, allowing it to withstand the heat generated during operation.
Is carbon wire still in light bulbs?
Modern light bulbs are made of tungsten wire.
Why does tungsten heat up and copper doesn't?
It has a higher resistance to the flow of electricity. Pushing a current through it will create heat. Tungsten is only about 3 times the resistance of copper per same cross sectional area and length. Copper will heat up as well given enough current. If you think about a 60 Watt incandescant bulb operating at 120 VAC it draws 1/2 an amp and the metal filament must be 240 ohms in resistance. If you examine the filament you'll see it is a coil of wire so that the required length can fit into smaller space. If the filament were made of copper you would need 3 times the length of wire to get the same resistance.
Copper wire and heat makes?
Hot copper wire. HTH. HAND.
Can copper wire withstand heat?
yes from copper wier withstand heat
Which is a better conductor of heat air or a copper wire?
A copper wire is a much better conductor of heat than air is.
What is tungsten wire what is it made up of?
Tungsten wire is a very thin wire that is made up of the element tungsten. It is known for its high melting point, strength, and resistance to corrosion, making it ideal for use in various electrical and heating applications. Tungsten wire is commonly used in light bulbs, electronic devices, and heating elements.
Why tungsten metal wire is not used in heater?
A heater does not get hot enough to benefit from the expense of using tungsten wire. Most heaters use either wire made of an alloy called nichrome or plated ceramic heating elements. Heaters generally operate at red or orange heat (i.e. 1409F to 1908F) and can use nichrome wire. Lightbulbs operate at white heat (i.e. greater than 2309F) and use tungsten wire, but tungsten is hard and expensive to make into wire compared to softer metals.
What is the name of the wire in a light bulb?
Filament. Correct; made of tungsten wire in most incandescent bulbs.
When current passes why copper wire does not get heated while the bulb gets heated?
copper wire is good conductor of heat but bulb is bad conductor of heat.
