What thin wire inside a light bulb is a?
Its a coiled tungsten filament.
What is the thin wire inside a bulb called?
It is called a filament and usually made of tungsten steel.
What is a filament resistor?
A filament bulb resistor is the common type of light bulb. It contain a thin coil wire called filament. It produces light as a result. It is made mainly from the element tungsten. The metle tungsten has very high melting point and it is a good conductor of electric current
Sentence with filament?
Filament was made from plastic. The filament was very stable and smooth.
What causes light bulbs to go smokey?
This is actually really cool. The tungsten filament evaporates and condenses on the bulb wall, leaving a thin tungsten film.
What is the thin coil of wire inside a light bulb called?
If you are talking about an incandescent light bulb then its called a filament. It is thin so that it has a high level of resistance. Current going through the filament causes it to heat up and give off EM radiation in the spectrum of visible light.
How do you Use filament in a sentence?
(Filament is a thread or thin wire.)Is the lamp unplugged or is the filament broken in the bulb?A silkworm's cocoon is made from a thin filament which can be twisted into thread.
How is the filament of the light bulb a resistor?
Most simple incandescent light bulbs are made of a thin section of tungsten through which the current flows. This section of tungsten is called a "filament". The tungsten filament has electrical resistance and so is a resistor. As a resistor it develops a voltage drop. This voltage drop multiplied by the amperage passing through it equals the wattage of the bulb. The heated tungsten gets to thousands of degrees above room temperature and becomes hot enough to produce yellow-white visible light. As a resistor, the tungsten light bulb has a positive resistance coefficient. This means that the electrical resistance goes up when the filament becomes hot. For example, a 100 watt light bulb operated at 120 volts - it does not matter if it is AC or DC for this calculation - will have a resistance of 144 ohms when hot and draw .833 ampere. When cold the filament typically has a resistance of only 10 ohms which increases as the filament heats up.
What is light bulb filament?
It is the extremely thin wire inside the bulb. It is so thin that when the electricity goes through produce light, when that filament breaks the bulb is not good.
What causes a light bulb to turn black when they burn out?
As an incandescent light bulb is used, tungsten slowly evaporates from the filament causing it to get thinner. When it gets too thin it can no longer carry the current and part of it melts causing the bulb to blow out.
What actually gives off light in a light bulb?
Electric current through a filament (thin spiral) of tungsten causes it to heat up enough to glow brightly.
What is the thin wire in the bulb called?
filament
