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.

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.
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
Whai is the difference in 3156 and 3157 bulb?
The main difference between a 3156 and 3157 bulb is the number of filaments they have. The 3156 bulb has one filament, typically used for signal lights, while the 3157 bulb has two filaments, making it suitable for dual-function applications like brake lights that also serve as tail lights. Make sure to choose the correct bulb type for your specific automotive lighting needs.
Are Bright centers of solar activity are called filaments?
No, bright centers of solar activity are not called filaments. Filaments are dark, cooler regions seen in the Sun's atmosphere known as the chromosphere. Bright centers of solar activity are often called active regions or solar flares.
There are three bulbs of 600W 100W and 200W which bulb has thickest filament?
600w - the thicker filament has a lower resistance, which leads to a higher current and thus higher wattage
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 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 is the use for tungsten?
Light bulb filaments.
Where is the coiled filament on the light bulb?
The coiled filament in a light bulb is typically located at the center of the bulb inside the glass envelope. This filament is what heats up and produces light when an electric current passes through it.
What is used to make globe filaments?
The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament. In 1906 the tungsten filament was introduced
Why the energy saver bulb is coiled?
To have enough bulb or surface area to produce the required amount of light.
Does an energy saver coiled bulb continue to flicker when switched off?
no
A three -way light bulb has 3 filaments?
A three-way light bulb actually has two brightness levels, not three filaments. It achieves this through a combination of filaments that can be turned on in different combinations to produce different levels of light.
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.
What did Joseph swan make the light bulb out of?
He made it out of carbonized paper filaments in an evacuated glass bulb.
