Copper has much less resistance, so the electricity flows thru it with little heat, where as the tungsten resists the flow and generates heat, that you see as light.

What causes filament in a light bulb to glow?
Current passing through a special wire like tungsten heat up the wire and create light by emitting photons
What thin wire inside a light bulb is a?
Its a coiled tungsten filament.
The light emitted by an incandescent element produces what?
A unique continuous spectrum
What is the filament of a light bulb?
It's the small coil of very fine tungsten wire that glows white hot.
What makes a light bulb glow when a lamp is turned on?
In an incandescent light bulb a small coil of thin tungsten metal - which is not such a good conductor of electricity as copper - resists the flow of current so much that it heats up. The thickness of the tungsten is carefully designed so that it gets hot enough to give out visible light but does not get so hot that it melts and breaks.Another answerInside the bulb is a wire that goes to a piece of coiled tungsten (a heavy metallic element). This causes maximum resistance to the electricity flowing through the wire. The resistance causes the tungsten to heat up to 4,500 degrees F, so much that we see the glow as light. The glass bulb surrounding it contains an inert gas, protecting the filament from oxygen which would cause it to burn out immediately and also prevents contact with the white hot metal.For more information please click on the Related Questions shown below.
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.

Is carbon wire still in light bulbs?
Modern light bulbs are made of tungsten wire.
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 thin wire inside a light bulb is a?
Its a coiled tungsten filament.
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.
How are batteries connected in a flashlight?
The electrons from the battery go through the wiring to the bulb. Inside the bulb, they heat a tungsten wire so hot that it glows, giving off light.
