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 .
What is a light bulb filament?
the filament is the metal peice in a bulb that glows.Tungsten is most often used in a lightbulb.
What is electrical energy converted into when electric current flows through the metal filament of a light bulb?
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Why does the filament in a light bulb not burn up immediately?
The 'Filament' of a lightbulb is a peice of metal with an unusually high melting
Why does the light bulb light?
A bulb lights up because of the friction happening between the atoms usually in the metal filament. thus producing light.
What type of light is a light bulb that uses a filament?
A light bulb that uses a filament is also known as an incandescent light bulb.
Why does the light bulb light up?
A bulb lights up because of the friction happening between the atoms usually in the metal filament. thus producing light.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
When electric energy flows through the metal filament of a light bulb energy is converted to?
Heat, which then produces light.
When electricity flows through the metal filament of a light bulb electrical energy is converted to?
Heat, which then produces light.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Why is argon used instead on air in the light bulb?
The filament in the light bulb is heated to a very high temperature. At such a temperature oxygen from the air would oxidise the metal(s) in the filament and thereby destroy the bulb. Using an inert gas such as argon in the bulb prevents such oxidation.
