What items contain tungsten?
Electric bulb Filament
Why do lamp filaments age?
The high temperature causes a small amount of the metal in the filament to evaporate away. Over some time, the filament will develop a "hot spot" where it is thinner than the rest of the filament, which causes more rapid degradation and the filement will "blow".
What elements are in light bulbs as a filament?
Light bulb filaments are usually made of tungsten, which has a very high melting point. Occasionally carbon is used as a filament.
What element is used for a filament for light bulbs?
Tungsten
Why are V-i characterstics different for tungsten and carbon lamp?
As carbon filament bulbs have a negative temperature coefficient and tungsten filament light bulbs have a positive temperature coefficient.
Do incandescent bulbs contain a filament of platinum?
yes, incandescent bulbs do not contain a filament of platinum. Yes they do contain a filament called a tungsten.
What items contain tungsten?
Electric bulb Filament
Is mercury used for the filament in light bulbs?

What does a photo flash bulbs contain?
lots of tungsten filament wire
Which filament is for brake lights on 2002 Chevy Express 2500?
The standard 1157 or similar two filament bulbs contain an upper (small diameter) filament for the parking lights and a lower (larger diameter) filament for the brake and flasher applications. The new LEDS operate from one diode.
Do you have to have the glass on the outside of the light bulb?
Yes, it is used to contain the inert gas that surrounds the filament.
What does the male part of a flower contain?
The filament(s) and the anther(s) make up the male part of the flower.
What contains filament?
Microfilaments contain actin filaments. They are the thinnest filaments of the cytoskeleton, which is a structure found in the cytoplasm of eukaryotic cells.
What supports the anther?
The Filament
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
What is the part of a flower which holds up the anther?
Filament
Sentence with filament?
Filament was made from plastic. The filament was very stable and smooth.
