They have to be coiled in order for them to be long enough to produce enough heat, which produces the light in a small space. Otherwise the light bulb would have to be much larger.
A filament bulb is coiled to allow a much longer filament to fit into a tiny space. It also reduces the amount of gas which flows across the inner portion of the filament.

∙ 9y agoA filament is coiled, because it will not receive power if it is in the shape of a straight line. If a filament is uncoiled, only a small portion of it will work.

What element is used in light bulb filaments?
Tugsten No, its Neon. like Neon signs actually its not neon because neon is used for neon lights the questions states what is used in light bulb filaments not neon lights.
Are Bright centers of solar activity are called filaments?
yes like the bright filament of a light bulb
Which metal has a melting point of over 3000 degrees celsius is used to make light bulb filaments?
The filament wire of an incandescent light bulb is a tightly-coiled wire made from Tungsten. Before it is coiled up it is long and thin.The element is always supported on two stronger wires made of another kind of metal which can withstand the intense heat inside the bulb.Another answerThere are many different kinds of light bulbs that use other metals! Just to name a few: Mercury(Hg), Tungsten(W), Sodium(Na).Tungestun
Why won't a three way lamp switch work with a wall controlled outlet?
Not wanting to state the obvious but the wall switch has to be turned on to supply voltage to the outlet. The lamp will need a three way light bulb in the lamp. A three way bulb uses two filaments of different lengths. One element is used for low brightness, the other filament for medium brightness and the high brightness setting uses both filaments in the bulb. If a single filament ordinary light bulb is used in place of a three way light bulb there will be a position on the three way lamp switch where the bulb will not light. Find the position on the lamp where the bulb will light and leave it there. Use the wall switch to turn the lamp off and on through the controlled receptacle.
What causes the left tail light not to get brighter when braking even though both bulbs light up when the lights are turned on on a Dodge Stratus?
Many taillight assemblies are equipped with bulbs with dual filaments, one for tail lights and one for brake lights. If you have one bulb with two filaments, then the problem you describe sounds like the brake light filament in the left bulb is burned out but the tail light filament is working.
What is always in light bulb filaments?
Tungsten is always in light bulb filaments :)
What makes up myofibrils?
Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. Thick filaments consist primarily of the protein myosin, held in place by tit in filaments.
Which metal used in filaments?
Generally 'Tungstan'is use in bulb filaments.
What is the use for tungsten?
Light bulb filaments.
What improvements were gradually added to Thomas Edison's original light bulb?
in 1911 tungsten was introduced as a filament. In 1913 filaments were coiled for the first time, and bulbs were filled with inert gas. Beginning in 1925, bulbs were frosted on the inside
What element makes light bulb filaments?
Tungsten
Olfactory nerve filaments are found?
in the olfactory bulb
Why the energy saver bulb is coiled?
To have enough bulb or surface area to produce the required amount of light.
What did Joseph swan make the light bulb out of?
He made it out of carbonized paper filaments in an evacuated glass bulb.
Does an energy saver coiled bulb continue to flicker when switched off?
no
What thin wire inside a light bulb is a?
Its a coiled tungsten filament.
1996 jeep Cherokee only one head head light works but both work when you turn on high beams?
Bulb problem - The bulb actually has 2 filaments in it and one of the filaments has burned out, replace bulb problem fixed.
