Electricity

Petroleum can also be used to make steam to turn a turbine. Residual fuel oil, a product refined from crude oil, is often the petroleum product used in electric plants that use petroleum to make steam. In a nuclear power plant, a reactor contains a core of nuclear fuel, primarily enriched uranium. When atoms of uranium fuel are hit by neutrons they fission split , releasing heat and more neutrons. Under controlled conditions, these other neutrons can strike more uranium atoms, splitting more atoms, and so on.

Thereby, continuous fission can take place, forming a chain reaction releasing heat. The heat is used to turn water into steam, that, in turn, spins a turbine that generates electricity. In , Nuclear power is used to generate As of , hydropower accounts for 6. Its a process in which flowing water is used to spin a turbine connected to a generator. There are mainly two basic types of hydroelectric systems that produce electricity.

In the first system, flowing water accumulates in reservoirs created by the use of dams. The water falls through a pipe called a penstock and applies pressure against the turbine blades to drive the generator to produce electricity. English Wikipedia has an article on: Etymology of electricity. It is therefore considered a sure indicator of the presence of electricity in an active state, and forms the basis of all its tests.

Electrons revolve around the nucleus in shells. The protons and electrons of an atom are attracted to each other and each carries an electrical charge. Protons have a positive charge and electrons have a negative charge. The positive charge of the protons is equal to the negative charge of the electrons, making the atom balanced when they have an equal number of protons and electrons.

Neutrons carry no electric charge and their number may vary. The electrons in the shell closest to the nucleus have a strong attraction to the protons. These shifting electrons are electricity. A few protons and electrons can form bigger particles called atoms and molecules. Atoms and molecules are still very tiny. They are too small to see. Any big object, like your finger, has more atoms and molecules in it than anyone can count. We can only estimate how many there are.

Because negative electrons and positive protons stick together to make big objects, all big objects that we can see and feel are electrically neutral. Electrically is a word meaning "describing electricity", and neutral is a word meaning "balanced. All big objects are electrically neutral because there is the same amount of positive and negative charge in the world. We could say that the world is exactly balanced, or neutral. Scientists still do not know why this is so.

The electrons can move all around the material. Protons never move around a solid object because they are so heavy, at least compared to the electrons. A material that lets electrons move around is called a conductor. A material that keeps each electron tightly in place is called an insulator. Examples of conductors are copper, aluminum, silver, and gold.

Examples of insulators are rubber, plastic, and wood. Copper is used very often as a conductor because it is a very good conductor and there is so much of it in the world. When the same mysterious force energizes a loved one's touch, a stroke of lightning and a George Foreman Grill, a curious duality ensues: We take electricity for granted one second and gawk at its power the next.

More than two and a half centuries have passed since Benjamin Franklin and others proved lightning was a form of electricity, but it's still hard not to flinch when a particularly violent flash lights up the horizon.

  1. Electricity, phenomenon associated with stationary or moving electric charges. Electric charge is a fundamental property of matter and is borne by elementary particles. In electricity the particle involved is the electron, which carries a charge designated, by convention, as negative.
  2. May 26,  · Electricity is both a basic part of nature and one of the most widely used forms of energy. The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear .
  3. Sep 24,  · Electricity is a basic part of nature and it is one of our most widely used forms of energy. We get electricity, which is a secondary energy source, from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
  4. Define electricity. electricity synonyms, electricity pronunciation, electricity translation, English dictionary definition of electricity. n. 1. a. The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and.
  5. Electricity definition is - a fundamental form of energy observable in positive and negative forms that occurs naturally (as in lightning) or is produced (as in a generator) and that is expressed in terms of the movement and interaction of electrons. How to use electricity in a sentence.
  6. Electricity is a secondary energy source that we get from the conversion of other sources of energy such as coal, natural gas, oil, nuclear power, and so on. These sources are known as “primary sources.” Primary sources can be renewable or non-renewable, but the electricity itself is neither.
  7. Electricity powers our world and our bodies. Harnessing its energy is both the domain of imagined sorcery and humdrum, everyday life -- from Emperor Palpatine toasting Luke Skywalker, to the simple act of ejecting the "Star Wars" disc from your PC.
