Admin What is electrical foot contact?
The base of an incandescent light bulb is comprised of two metal contacts. The ELECTRICAL FOOT CONTACT forms the very bottom of the bulb; the SCREW THREAD CONTACT is the grooved metal band at the base of the GLASS BULB. Each contact is connected to a metal CONTACT WIRE.
What are the main parts of a light bulb?
Parts of a light bulb: the glass globe, the metal filament, wires and glass stem, gases and metal base.
What is electrical foot contact made of?
metal contact
Coming up from the electrical foot contact are two metal contact wires. These wires are very stiff and are attached to a tungsten filament. A filament in a light bulb is a wire that is almost as thin as a thread.
What are light sockets made of?
Phenolic lamp sockets are made of phenolic resin. This plastic material is known for its resistance to heat, strength, and non-conductive characteristics. In the early days of lamp sockets, a material called Bakelite was used to manufacture these sockets.
What is the electrical foot contact of a light bulb?
The electrical foot contact is at the base of the bulb and connects it with an electricity source. Coming up from the electrical foot contact are two metal contact wires. These wires are very stiff and are attached to a tungsten filament. A filament in a light bulb is a wire that is almost as thin as a thread.
How does an electric light bulb work?
The electrical foot contact connects wires to an electricity source. The tungsten filament is heated until it glows, and inert gases inside the glass bulb help keep the light bulb from catching on fire. To unlock this lesson you must be a Study.com Member.
What is inside a light bulb?
How Light Bulbs Work. The metal contacts are attached to two stiff wires, which are attached to a thin metal filament. The filament sits in the middle of the bulb, held up by a glass mount. The wires and the filament are housed in a glass bulb, which is filled with an inert gas, such as argon.
What are the two metal contact wires in a light bulb?
Coming up from the electrical foot contact are two metal contact wires. These wires are very stiff and are attached to a tungsten filament. A filament in a light bulb is a wire that is almost as thin as a thread. This wire is used to conduct heat, and it is made from a chemical element called tungsten.
