because it get very hot from resistive heating, is the simplest explantion. In a bit more detail, an incandescent object emits electromagnetic radiation in a band of frequencies determined by Planck's law. The filament is hot enough for the radiation to be in the visible band. for more info: http://en.wikipedia.org/wiki/Incandescent_light_bulb http://en.wikipedia.org/wiki/Incandescence http://en.wikipedia.org/wiki/Planck%27s_law
What else can I help you with?
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
Where is the coiled filament on the light bulb?
The coiled filament in a light bulb is typically located at the center of the bulb inside the glass envelope. This filament is what heats up and produces light when an electric current passes through it.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
What is light bulb filament element and symbol?
A light bulb filament is a coiled wire inside the bulb that heats up and produces light when an electrical current passes through it. The symbol for a light bulb filament is usually represented as a zigzag line inside a circle.
What is the filament inside a light bulb?
The filament inside a light bulb is typically made of tungsten. When electricity passes through the filament, it heats up and produces light through incandescence.
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
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 .
Where is the coiled filament on the light bulb?
The coiled filament in a light bulb is typically located at the center of the bulb inside the glass envelope. This filament is what heats up and produces light when an electric current passes through it.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.

What is the filament inside a light bulb?
The filament inside a light bulb is typically made of tungsten. When electricity passes through the filament, it heats up and produces light through incandescence.
The part of a light bulb that is a poor conductor so that the friction causes it to light up and glow?
The filament inside a light bulb is typically made of tungsten, which is a poor conductor of electricity. When electricity flows through the filament, it encounters resistance, which causes the filament to heat up and emit light.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
Did the bulb light in electrical energy?
Technically the bulb does not light, it is but a housing for the filament and electrodes. It is the filament that gives off the light as it is heated by the electricity passing through it. The bulb helps to scatter the light in equal proportions.
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 is light bulb filament?
A light bulb filament is a thin wire, typically made of tungsten, that is heated by an electrical current to produce light. As the filament heats up, it glows and produces light, making it a critical component in an incandescent light bulb.
What is the filament in a light bulb made of?
The filament in a light bulb is typically made of tungsten.
