Parts of an Incandescent Bulb
At first glance, an incandescent bulb seems simple, but it actually consists of several individual parts that have become standardized.
Screw Base: The familiar threaded base was developed by Edison and is known as the E-base. Today, several sizes exist.
Globe: The glass enclosure is known as the globe. The familiar pear-shaped one is most common because it distributes light better than other shapes. Frosted globes came on the market in 1925 and are still common.
Filament: In 1911, American physicist William D. Coolidge developed the tungsten filament, and General Electric quickly adapted it into their bulbs. It remains the standard bulb filament.
Contact wires: Thin wires extend from the filament to the screw base and the foot contact at the base of the bulb. They complete the electrical circuit when the bulb is screwed in.
Support wires: A pair of thin wires support the filament and prevent it from contacting the globe of the base when electricity is flowing
Answer:
-An electric bulb consists of a transparent glass covering. It encloses a thin, coiled metal wire known as the filament.
-The filament is made up of tungsten that is supported by two thick wires.
- One of these wires is connected to the metal base of the bulb. The other wire is connected to the tip at the bottom.
- The metal case and the tip at the bottom are the two terminals of the bulb.
