The element used in light bulbs filaments?
Tungsten
Why do light bulbs use very fine filaments?
Incandescent light bulbs use tungsten( a metal which can withstand very high temperatures) as filament.When heated to a very high temperature, the filament glows emitting light and heat. Heating effect in filaments is caused by the property of resistance in conductors. On reducing the cross- section area( thickness) of the filament, its resistance is increased and hence the filament glows with comparitively lesser electric current.
How does a light bulb turn on and off?
First, to explain the on/off switch:There is an electrical wire connected to the switch. When the switch is in the [ON] position, it is called a closed circuit, when electricity can run through to power the light bulb. When the switch is in the [OFF] position, the switch stops touching the wires, and it is called an open circuit, where the circuit is broken and the electricity cannot flow.Second, light bulbs:Normal incandescent light bulbs are powered when an electric current runs through their filament. Incandescent bulbs' filaments are very thin, and when electricity runs through them they become so hot they glow bright yellow to white.How come the filaments don't burn up? That was a problem Thomas Edison came across when he tried to make incandescent light bulbs; the filaments burned up. He solved that problem by making a vacuum inside the bulb - No air means no Oxygen, and no Oxygen means no burning. (vacuum means absolutely no gas or air inside an area.) However, he had to make very thick walls for that style of bulb. Today, we fill incandescent bulbs with non-reactive gas at the same pressure as outside air, so bulb walls can be nearly paper-thin.Please rate this answer! :D
What is the gas that does not react at all and it is used in light bulbs so the metal in the light bulb can get very hot without burning?
Argon
Do you use pig hair to make a light bulb?
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
How do the makers of light bulbs prevent filaments from burning out?
When the glass is sealed on the light in the build process the light is filled with an 'innert' gas. That means that the gas will not sustain fire or ignition.
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
The element used in light bulbs filaments?
Tungsten
What are carbon filaments for light bulbs?
Modern light bulb filaments are usually Tungsten not Carbon. However early bulbs used things like silk coated with Carbon. Filament means thin thread. The bulbs are filled with inert gas like Argon to stop the filament from burning up with oxygen. Arc lamps use Carbon rods though.
What element makes up the filaments in light bulbs?
It is usually Tungsten.
Which element is used in the filaments of household light bulbs?
usually tungsten
How many filaments exist in a light bulb?
Most incandescent bulbs have one filament. Some halogen bulbs working on 240 v have two filaments in series, which must be to simplify manufacture of bulbs being made for 120 v and 240 v in the same factory.
Element used in light bulb filament?
That depends on the bulb, and the time frame. The first bulbs had carbon filaments. Certain bulbs used in control devices have iridium filaments. Modern grocery store incandescent bulbs have tungsten filaments.Tungsten, because of its very high melting point.
What element is found in filaments of electric bulbs?
Tungsten is the main one. There may be others.
What element is commonly found in filaments in incandescent light bulbs?
Tungsten, as it burns long and brightly.
What could cause the brake-lights on a 1990 Volvo to work with the headlights off but not to work when the headlights are turned on?
They are either the wrong bulbs or one of the filaments is burned out. The bulbs should have two filaments. One is illuminated when the lights are on. The other is brighter when the brakes are used.
What is an anode made from?
Anode is the negative terminal of a battery. It is made of Tungsten which is the same metal used in the filaments of bulbs.
