Bill takes apart an incandescent light bulb to how the filament is made. Best Answer: Whoever made up that question knows nothing about light bulb filaments. That resistivity value applies only at about 25°C. Bulbs are made in various shapes and finishes. Click to view various incandescent light bulb shapes. B) Filament: The filament material is generally tungsten. Now take a short quiz on the essential features a filament material should have. This lack of air or specifically oxygen in the bulb keeps the heated filament from being burned up faster. How does an incandescent light bulb work? Incandescent lamps produce light by heating a filament. How does an incandescent light bulb work? In 1906, the General Electric Company was the first to patent a method of making tungsten filaments for use in incandescent light bulbs. In modern incandescent bulbs, the most common filament material is tungsten. The filament inside a light bulb is made of tungsten because it has an are slowly edging out the old reliable light bulb. to use an energy efficient light bulb, but you think that they look funky? How about a LED bulb that looks and functions almost exactly like an incandescent filament bulb?
YAHOO! CANADA ANSWERS - THE FILAMENT IN AN INCANDESCENT LIGHT BULB.
Upon initialization, the tutorial window displays a coiled filament similar to those utilized in the common incandescent lamp, or light bulb. An electric current passes through the filament, heating it to a temperature that produces light. Incandescent light bulbs have been around for a long time and Matthew Evans filed the first light bulb patent. Today's incandescent light bulbs greatly resemble Edison's original lamps. However, all incandescent light bulbs have the three basic partshe filament, the bulb and the base. Answer to The tungsten filament of an incandescent light bulb has a temcontinues. Incandescent light bulbs have filaments which are made mainly from the element tungsten and/or alloys which include tungsten. This unit consists of an doesn't appear to be valid for the filament resistance of the light bulb. Edison had built his first high resistance, incandescent electric light. In 1906, the General Electric Company patented a method of making tungsten filaments for use in incandescent light bulbs. This is covered by Part II of the Great Internet Light Bulb Book, Discharge Lamps.

Answer to The filament in an incandescent light bulb is made from tungcontinues. Best Answer: Whoever made up that question knows nothing about light bulb filaments. That resistivity value applies only at about 25°C. The most common example of incandescence is the white-hot filament in the light-bulb of an incandescent lamp. An incandescent light bulb and its glowing filament. Contributions to the development of the incandescent lamp were made by several researchers. A normal light bulb is also known as an incandescent light bulb. These bulbs have a very thin tungsten filament that is housed inside a glass sphere. 1850 - Edward Shepard invented an electrical incandescent arc lamp using a charcoal filament. Incandescent light bulbs work by passing electricity through a thin wire (filament) made of tungsten which then heats up and gives off light. In a 60-watt bulb, the coil is less than an inch long.
THE HISTORY OF THE INCANDESCENT LIGHTBULB.
Tungsten is used in nearly all incandescent light bulbs because it is an ideal filament material. The incandescent light bulb, incandescent lamp or incandescent light globe produces light by heating a filament wire to a high temperature until it glows. Generally, an incandescent light bulb filament is most likely to “burn out# Tuesday, February 23, 2010 at 1:19pm by Joseph.
