How is eletrical energy converted in light energy?
In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light.In an incandescent light bulb, the wire is heated until it glows.In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels.

As well as light what else does a light bulb produce?
It kinda depends on what kind of bulb incandescent lights use filaments and emit heat, for example
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
How does a dry cell make a lightbulb light?
When electric current flows through filament of the bulb, the electrons are squased among themselves due to the thin structure of the bulb. This causes them to emit light. Due to the gases filled in the light bulb, the bulb glows.
What energy trasnformations occur in a incandescent light bulb?
In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
Does a light bulb emit carbons when used?
the electricity used to power the light bulb emit carbon dioxide
What is the use of bulb in the circuit?
To emit the generated light?
What is the use of the bulb in the circuit?
To emit the generated light?
How much carbon dioxide does each light bulb emit?
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
Would a warm white bulb emit more lumens than a white bulb?
It depends on the efficiently of the bulb, check the box to find the answer to this one.

Why white light emit light?
Light doesn't emit light, but other things do, like stars for example. Many things give off light, but white light is the only visible light, and is made up of many different colors, like a rainbow. The sun and other stars emit such light.
Are lightbulbs edible?
No, donuts are better but they do not emit light unfortunately. So there is an opening for the edible light bulb and the light-emitting donut.
What will happen to the light bulb when you switch off the electric circuit?
There will no longer be current to heat the filament which will then cool and no longer emit visible light. While it is cooling it will continue to emit infrared light for a time.
Why do satellites suddenly emit a very bright white light?
Planets cannot emit light. They merely reflect light from nearby stars.
How does a dry cell make a lightbulb light?
When electric current flows through filament of the bulb, the electrons are squased among themselves due to the thin structure of the bulb. This causes them to emit light. Due to the gases filled in the light bulb, the bulb glows.
