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 do you have a light bulb?
Light bulb provide electrical light.
What does a complete circuit need to make electrical devices work?
A source of electrons, a path, and something to use the electrons.
If the electrical conductivity in an electrical circuit decreases then the birghtness of the light bulb does what?
It decreases
When the light bulb is lit electrical energy is changed into light energy and?
When lighting a light bulb, it is changed into light and heat/thermal energy.
Does a light bulb convert electrical enegry into motion?
No
To light up a light bulb we need to connect to a?
To light a light bulb you need to connect to a source of electricity like a battery or an electrical outlet.
Is a bulb a light source?

If someone takes a aluminum can and attach a light bulb to it will it light up?
No, there needs to be an electrical source
Is a light bulb a source?

What happens to electrical energy when a light bulb lights?
It goes back to that source
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
Is a light bulb a source of an electric current?
No. The term SOURCE means that it is a supply of electrical energy, and a light bulb does not supply electricity, it uses it. A battery, generator, fuel cell, or solar cell would be a source.
What is the job of a light bulb?
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
Why do you have a light bulb?
Light bulb provide electrical light.
What is the source of energy in a light bulb?
Electricity is the source of energy in a 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.
Is light from the sun the same thing as light from a light bulb?
no because light from the light bulb is electrical and the sun is not
