What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.
Do you use pig hair to make a light bulb?
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
Why does the light bulb not work when the filament is broken?
A light bulb works by passing an electric current through the filament, which is usually made from a high resistance substance such as tungsten. When the current flows through, the filament glows which produces the light. When it burns out, no electricity passes and no glowing occurs. Source: i just know
How does the filament in a light bulb work?
it is made of tungsten and is a resistor when current flows thru it it heats up and glows
How did Thomas Edison make the first light bulb?
he woked on it for 15 years. He first made a airless glass that has the shape of a sphere and then he put in a filament (string that powers the light bulb) which was made out of carbon and powered the lightbulb through electricity
What is a light bulb wire made out of?
A light bulb is made out of three items. A filament produces the light, glass gives the light bulb shape and controls the brightness, and the base allows the bulb to be placed in a socket.
Who made the light bulb filament?
lewis latimer
How was the carbon filament a help to people?
It made the light bulb have light.
What is now days light bulb filament made out of?
tungsten
What do the wires in the middle of a light bulb do?
The filament is made of tungten and these 'wires' (filament) conduct electricity.
What is metal with which the filament is made?
Assuming you're talking about light bulbs... the filament is made from Tungsten.
What is the part of a light bulb that gets hot and produces lights?
In an incandescent light bulb this is the filament. It is usually made of tungsten.
What forms of energy does the electric light bulb made?
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
Why do you need to have the glass on the outside of a light bulb?
The glass envelope, or bulb, of an incandescent light bulb is needed to hold the inert gas, such as argon, that fills the space. The filament of a light bulb is made of tungsten wire. When electricity passes through it the filament becomes extremely hot and emits light. The inert gas surrounding the filament protects it from evaporating too quickly. A light bulb only lasts as long as its filament lasts.
What is the metal of a light bulb made of?
The wire inside of an electrical light bulb is called a "filament". The word filament comes from the Latin word "filum" which means "thread". In various fields there are many different types of filaments with different uses, however the ones inside of light bulbs are made out of tungsten and work by super-heating by passing electricity through it.
What is the metal thing on the light bulb called?
The metal thing in the bulb that shines really has no definition. It is only a part of the mechanism. The "metal thing" is called the filament and they are usually made of tungsten, which is the metal with the highest melting point. Higher than steel, but not stronger than steel.
How tungsten filament made?
Tungsten filament is used in the creation of the light bulb. It can be made in different shapes like coiling, and horizontal or vertical helix.
