An electric current passes through a very thin filament of tungsten, which to some degree resists the current and heats up until it glows brightly. Other substances could be used, but tungsten has the advantage of having an extremely high melting point and staying strong at high temperatures.
What else can I help you with?
Is tungsten tougher that tungsten carbide?
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
The work done to move one electron in a light bulb is very small?
The work done to move one electron in a light bulb is small because electrons are lightweight particles with a small charge. The work done is a result of the electric field in the circuit, which provides the energy for the movement of electrons to create light.
Why do you think salt water can light the bulb but distilled water cannot?
Salt water conducts electricity and contains ions that can complete the circuit and allow the bulb to light up. Distilled water, on the other hand, is a poor conductor of electricity as it lacks ions and impurities needed to carry the electrical current.
How many electrons are in the filament of a light bulb?
I think you probably know that the flow of electrons causes the filament to heat up and glow when the electricity is switched on and you want to know the number of electrons in the electricity? Well, it doesn't work quite like that, the electrons are all in the electron shells of the tungsten atoms making up the filament and there are the same number of electrons in these shells (and thus he filament) whether the electricity is on or off. When electricity is on, the electrons (in the outer shells) hop from one atom to the next, no extra electrons get into the filament (electrons coming in at one end are balanced by electrons going out at the other end) While all atoms have electrons, not all elements have atoms with 'free' electrons to allow this hopping - these elements will not conduct electricity.
What is the Mass of one tungsten atom?
The mass of one tungsten atom is approximately 183.84 atomic mass units (amu).
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.
how did humphry make the light bulb?
Thomas Edison, not Humphry, is credited with inventing the first commercially practical incandescent light bulb. Edison's light bulb design involved a tungsten filament encased in a vacuum-sealed glass bulb, which could produce light continuously for extended periods. Edison's work on the light bulb was a result of years of experimentation and improvement on previous designs.
How does an incandesent light bulb work?
An incandescent light bulb produces light by passing an electrical current through a filament, usually made of tungsten, which heats up and emits light as it glows white-hot. The glass bulb that encases the filament is filled with inert gas to prevent the filament from oxidizing and burning out.
How does the filament in a light bulb work?
The filament in a light bulb works by converting electrical energy into light and heat. When electricity flows through the filament, it heats up due to resistance in the material, causing it to emit light. The filament is typically made of tungsten because of its high melting point and durability.
Why does the electric bulb get light?
there is a filiament made of tungsten (wolfram; Wg) which is a special metal which shines bright at high temperature, converting the energy into light instead of heat. electricity is hot, and tungsten does not melt at high temperature. Furthermore, the vacuum inside of the bulb stops the tungsten from breaking. When a bulb is "blown", it is when the tungsten has broken which comes after lots of use, and therefore breaks the circuit of electricity. I think these bulbs are now illegal in western countries because of environmental hazards, and i have no idea how fluorescent or compact flourescent bulbs work let alone any other kind of bulb that exists now. but tungsten globes were what were light bulbs for many decades, and the ones which Thomas Edison started with.
How did Edison's light bulb work?
Electricity goes through the "electrical foot contact", heats up the wires (connected to the tungsten filament) therefore lighting the light bulb up. The filament is supported by wires. The glass mount holds up the two wires connected to the filament. That is how I think the light bulb works. Have a look.

What did Einstein do 100 times to get it to work?
To build the light bulb.
What are the raw Materials that can light a bulb?
Some raw materials that can light a bulb include electricity (from a power source), a filament (usually made of tungsten), a glass bulb to contain the filament, and inert gases like argon or nitrogen to prevent the filament from burning. These materials work together to produce light when the filament heats up and emits photons.
What are the two connecting points on an incandescent light bulb?
The two connecting points on an incandescent light bulb are the base and the filament. The base, typically made of metal, connects to the electrical socket, providing power to the bulb. The filament, usually made of tungsten, heats up and produces light when electricity flows through it. These components work together to convert electrical energy into light.
How does a light bulb work to produce lighting?
A light bulb works by passing electricity through a filament, which heats up and produces light. The filament is usually made of tungsten, which has a high melting point and can withstand the heat. The electricity flows through the filament, causing it to glow and emit light. The bulb is filled with an inert gas, such as argon, to prevent the filament from burning up. The combination of the heated filament and the gas inside the bulb produces the light that we see.
Does the middle bulb on the tail light work?
If there is a bulb, it should work.
