What does the filament of a light bulb do?
The filament of a light bulb is the thin wire that heats up and emits light when an electric current passes through it. This process is known as incandescence, where the filament produces light as it gets heated to high temperatures.
Why does a light bulb filament glow?
A light bulb filament glows when electricity passes through it, causing the filament to heat up and emit light due to incandescence. The high temperature of the filament makes it glow and produce visible light.
How the filament is heated?
The filament in a light bulb is heated by passing an electric current through it, which causes the filament to resist the flow of electricity and heat up due to its electrical resistance. The heat generated by the filament causes it to emit light, producing illumination.
Which type of light bulb glows when a filament inside it gets hot?
Incandescent light bulbs produce light when a filament made of tungsten wire is heated by an electric current flowing through it. The filament glows and emits light as it reaches high temperatures.
Why do light bulbs glow?
Light bulbs glow when electricity passes through the filament, causing it to heat up and emit light. The filament is made of a material that has high resistance, which generates heat when the current flows through it. As the filament heats up, it emits light due to its high temperature.
What happens when a filament gets heated?
the bulb get fused
When electricity pass through the bulb what happens to the filament?
It gets heated up and glows spreading the light
Why the filament in a bulb lights up?
because filaments are generally good conductors of heat , so the filament burns first and then gets heated up and then gives light.
What does the filament of a light bulb do?
The filament of a light bulb is the thin wire that heats up and emits light when an electric current passes through it. This process is known as incandescence, where the filament produces light as it gets heated to high temperatures.
What is an incandascent lamp?
Your standard light bulb where a filament is heated by a current passing through it. The heated filament then gives off light.
What is the functions of a filament in an electric bulb?
To produce the light. When it gets heated, it glows.
Why does a light bulb filament glow?

Which type of light bulb glows when a filament inside it gets hot?
Incandescent light bulbs produce light when a filament made of tungsten wire is heated by an electric current flowing through it. The filament glows and emits light as it reaches high temperatures.
What is light produced by?
A filament is heated by an electric current and photons are emitted.
What does filament contain?
A filament typically contains a material, such as plastic, metal, or glass, that is used as the main component in 3D printing and lighting applications. In 3D printing, the filament is heated and extruded layer by layer to create a physical object, while in lighting, it is heated to create light.
Difference between direct and indirect cathode ray?
In a directly heated cathode, the filament is the cathode and emits the electrons. In an indirectly heated cathode, the filament or heater heats a separate metal cathode electrode which emits the electrons.
