Flourescent bulbs. They have no filament and they light up. They have argon gas and a small amount of Mercury in them. When electricity is added, the argon and mercury atoms get excited and collide against each other and create light. The light is ultraviolet light and if the bulb is not coated inside with phosphorous, you have a black light.

What is the function of a filament bulb?
A filament bulb functions by passing an electric current through a thin wire filament, typically made of tungsten, which heats up and produces light as a result of incandescence. As the filament reaches high temperatures, it emits visible light, making the bulb useful for illumination. However, filament bulbs are less energy-efficient compared to modern alternatives like LED bulbs, as much of the energy is lost as heat rather than light.
How efficient is a filament light bulb?
Filament light bulbs are not very energy efficient, converting only about 5-10% of the electricity they consume into light, while the rest is lost as heat. This inefficiency is why other types of lighting like LED have become more popular for their energy-saving benefits.
What does a tungsten filament do?
A tungsten filament is a key component in incandescent light bulbs. When an electric current passes through the filament, it heats up to a high temperature, causing it to emit light. Tungsten is used because of its high melting point and excellent conductivity, allowing it to glow brightly without melting. This process is known as incandescence, where the filament produces light as it becomes hot.
Do bulb make use of magnets to work?
No, bulbs do not make use of magnets to work. Light bulbs function by passing electricity through a filament, which then emits light and heat. Magnets are not involved in the process of generating light in bulbs.
Does current transfer energy provided by bulbs?
No. Bulbs use energy, they don't provide it.
What makes up the filament of light bulbs?
Filament of light bulbs are made up of Tungsten.
Why bulbs light?
Bulbs light up when an electric current passes through the filament, which heats up and emits light. This process is called incandescence.
How does a light bulb light?
light bulbs have metal contacts that connect to an electrical circuit and a filament. power lights up the filament in the bulb .
Is mercury used for the filament in light bulbs?
No, not in the filament. You are probably thinking of compact fluorescent light bulbs, which do contain mercury.
Why do light bulbs have the coil in the middle?
That is the filament. Electricity traveling through the filament heats it to the point of glowing brightly - that is the light bulbs "light".
What happens to the filament when light bulbs blows?
The filament breaks.
What element do you find in light bulbs?
Light bulbs contain a filament, typically made of tungsten, which produces light when electricity passes through it and heats up. This process causes the filament to emit light and illuminate the surroundings.
What is in filament of light bulbs?
tungsten
What kind of light bulb uses filament?
Incandescent light bulbs use a filament made of tungsten to produce light. The filament heats up when an electric current passes through it, emitting light as a result.
How available are filament light bulbs?
I have not had any problem obtaining incandescent light bulbs.
What are domestic light bulbs?
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
What is the thickness of the filament in light bulbs?
the filament is neither too thick nor too light
