How many apples does it take to light a light bulb?
It would take a lot of apples to generate enough electricity to light a light bulb. Apples can produce a small amount of electrical current through a process called oxidation, but it would likely require hundreds or even thousands of apples to power a light bulb.
Was the first light bulb in the world made by Thomas Edison?
No, the first light bulb was not made by Thomas Edison. The first practical incandescent light bulb was developed by Joseph Swan in the UK. However, Edison's version was more commercially successful and widely adopted.
Would a light bulb light up when placed in an aqueous solution of sodium chloride but not solid sodium chloride?
The light bulb would not light up when placed in a solid sodium chloride because the solid does not conduct electricity. However, in an aqueous solution of sodium chloride, the solution is able to conduct electricity due to the presence of free ions, allowing the light bulb to light up.
Can i light a light bulb with a battery and a paper clip?
It is possible to light a small LED light bulb using a battery and a paper clip, as long as the paper clip is used to create a closed circuit between the battery's terminals and the light bulb. However, be cautious as this setup can potentially overheat and cause a fire hazard. It is always safer to use proper tools and equipment designed for this purpose.
Who is the first scientist who discover a bulb?
Thomas Edison is credited with inventing the first commercially practical incandescent light bulb in 1879. However, Sir Humphry Davy created the first electric light in 1802 by passing an electric current through a platinum filament.
What is the input or output of a light bulb?
The input of a light bulb is electricity, which powers the bulb, causing it to emit light as the output.
Is a light bulb renewable or nonrenewable?
The light bulb its self is non renewable, it is replaceable. The electricity that powers the light bulb can be renewable.
What powers the light bulb?
Electricity powers the light bulb by flowing through a filament inside the bulb, which causes it to heat up and produce light. The filament is typically made of tungsten, which has a high melting point and can withstand the heat needed for light production.
Why does a lemon light a bulb?
A lemon can power a light bulb because of the acid in it. The acid is used as a conductor and powers the lemon.
Where does the electricity go in a light bulb?
Electricity flows through the filament of a light bulb, heating it up and causing it to emit light. The electricity powers the light bulb, allowing it to produce illumination.
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
Why does a battery power a light bulb?
A battery powers a light bulb by converting stored chemical energy into electrical energy. When the battery is connected to the light bulb, a circuit is completed, allowing the flow of electrons through the filament of the bulb, which produces light and heat.
Does a flashlight change from chemical energy to light energy?
Yes, a flashlight changes stored chemical energy into light energy when the battery powers the light bulb. The chemical energy in the battery is converted into electrical energy, which then powers the light bulb's filament to produce light.
Where does the energy given off by the light bulb come from?
From the electric current that powers it.
What kind of energy makes the light bulb light up?
Electricity is the energy source that powers a light bulb and makes it light up. When electricity flows through the filament in a light bulb, it generates heat and light, resulting in illumination.
When a light bulb is lit electrical energy is changed into light energy and?
heat energy. The electrical energy powers the light emission in the bulb, producing both light and heat as byproducts of the process.
What is the change in the potential energy of a single electron as it moves through the light bulb?
As an electron moves through a light bulb, its potential energy changes due to interactions with the electric field. This change in potential energy is converted into light and heat energy, which powers the light bulb.
