What is the filament in lights?
Filament is a thin part of incandescent bulb which is the source of electric light that electric current passes through and heated it until it produce 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.
Is an electric light bulb a natural or artificial source of light?
yes
What source of light is shown in the diagram?
The diagram shows an incandescent light bulb as the source of light. It consists of a tungsten filament that emits light when an electric current passes through it, causing it to heat up and glow.
In 1800 Humphrey Davy invented the first electric light bulb. What scientific discovery made Davy's invention possible?
Humphry Davy's invention of the first electric light bulb in 1800 was made possible by Alessandro Volta's invention of the electric battery in 1800. The electric battery provided a stable and continuous source of electric current needed to power the light bulb.
What is bulb and its proccess?
A light bulb is an electric light that uses the process of a filament wire that is heated to produce an electrical current. When the electrical current passing throught the light bulb it produces light.
What gives out a light if an electric current flows through it?
A light bulb in an electric circuit when electricity reaches it.
Is a light bulb is a kind of lever?
No. A light bulb is a bulb that contains a filament that gets hot when electric current is passed through it.
How can an electric bulb be considered as an extended source of light an as point source of light?
Either, depending on the situation. If you look at it from far away, the light seems to come from a single direction, and can be simplified as a point-source. If you are very close, the light comes from different directions, and such a simplification is no longer correct.
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.
How do you describe a light bulb?
A light bulb is an artificial source of light that typically consists of a glass bulb containing a filament or LED that produces light when an electric current passes through it. It is commonly used for illumination in homes, offices, and other spaces.
When electric current flows through the metal filament of light bulb electric energy is converted to?
Heat and light.
