Electricity generation is based on the principle of electromagnetic induction, a scientific law that was discovered by British scientist Michael Faraday and American scientist Joseph Henry in 1831. The principle states that when an electric conductor, such as a copper wire, is moved through a magnetic field, electric current will flow through the conductor. The mechanical energy of the moving wire is converted into the electric energy. Faraday and Henry found that when you move a magnet in a coil of wire, electric current is generated.
Faraday's law of induction shows that a moving magnetic field will cause electrons to move. Generators create electron movement in the copper wire coils contained within by moving them through a magnetic field.
Generator magnets apply pressure to the electrons to push them and create a flow or current of electricity. The number of moving electrons is called the amperage or the current and is measured in amps. The pressure pushing the electrons is called the voltage and is measured in volts.
A generator is basically created by a mechanical force that turns a conductive wire or bar within a magnetic field. The force used to spin the conductive object can be provided by many sources, such as moving water, steam, wind, gas engine or even hand-cranked levers. The electricity then flows into an electric motor or other electric-powered device, which reverses the process and the electricity makes it move. Small generators create a magnetic field with permanent magnets. Larger generators create a magnetic field with a set of metal coils with electric current flowing through them; this is an electromagnet.
In simpler terms, when a copper wire passes through a magnetic field (anywhere near a magnet) the coppers electrons all start moving in the same direction. This will be one of two directions, depending on which end of the magnet is closer. As the magnet goes by the wire, electrons "chase" the magnet and flow down the copper wire, thus creating electrical power. If only one side of the magnet goes by the copper wire over and over, these electrons will only move in one direction. This form of power is called direct current (Electrons are flowing only one way). If the magnet rotates, the electrons will move in both directions. This is what you get from your wall and is called Alternating current (AC). Tesla is the man responsible for this concept and much of the modern power systems we take for granted.

Electricity is hard to explain because it is something we cannot see. It is unlikely that anyone will ever properly see electricity because the electrons, which it is made of, are so small. Electricity truly is an 'invisible force'.
But we can see what electricity does - the results of electricity's power - and we can understand it best by understanding how it is made and how it is used.
Everything in the world is electrical because all matter in the world - including the human body - is made up of atoms, and every atom is made up of a number of electrons and protons which are 'particles' of electricity. Once we have generated electricity we can make it do almost anything for us. Although electricity can be produced in many ways including natural sources (lightning, nerve impulses, static electricity) the major useful source for human consumption is mechanical power generation.
Electricity is typically generated by rotating a wire coil through a fixed magnetic field, using the kinetic energy to induce a current in the wire. Any source of mechanical energy can be used to spin a generator or alternator.
Mechanical sources include:
Non-generator sources of electricity are:
A coil of copper wire passing through a magnetic field will generate an electric current in the wire. This is the basis of the generating stations.
Electrical power is usually generated by electro-mechanical generators driven by steam produced from fossil fuel combustion, or the heat released from nuclear reactions; or from other sources such as kinetic energy extracted from wind or flowing water.
Electricity can be formed by:
1) Friction - static electricity
2) Magnetism - a conductor crossing a magnetic field
3) Chemical - stored charge in a battery
4) Light - solar panels
5) Pressure - some crystals under pressure will produce minute potentials, this electricity is called piezoelectric
6) Heat - a thermocouple is when to dissimilar metals are joined, when heated they will produce electricity
Electricity is formed due to the accumulation of electrons.
It is made with a generator. It exists in nature as static electricity such as lightening or the spark made when rubbing wool on metal or plastic.
Electricity can be made several ways; from steam, combustion gases or water, but all of these methods involve a turbine to concert kinetic energy into electrical energy. The turbine moves a magnet around a wire, which electrifies the wire. Then transformers are used to push the electricity on down the line away from the generator.

In the early 1800s, Michael Faraday discovered "electromagnetic induction", which is the scientific way of saying that if he moved a magnet through a loop of wire, the wire would become electrified.
In 1882, Thomas Edison opened the first full-scale power plant in New York City. Edison's electric generator was a bigger version of Faraday's basic experiment; a big magnet rotates around a wire to produce an electric current.
Today's power plants are bigger and controlled by computers, but the basic process is still the same as it was nearly 120 years ago.
According to Faradys laws................ refer working of generators.......you can get better realization.
Earth does not "get" electricity as a natural resource. However, electricity can be generated through various methods on Earth, such as by burning fossil fuels, harnessing renewable energy sources like solar or wind power, or utilizing nuclear power, among other methods.
Geothermal electricity is generated by harnessing the heat stored beneath the Earth's surface to produce steam. This steam is then used to drive turbines connected to electrical generators, converting the mechanical energy into electricity. Geothermal power plants can operate 24/7, providing a consistent and renewable source of electricity.
No, electricity is not a gas. Electricity is a form of energy that results from the flow of electric charge. It is typically generated from various sources such as fossil fuels, nuclear, hydroelectric, or renewable sources.
Electricity generated from geothermal energy is produced by tapping into heat stored beneath the Earth's surface. This heat is used to boil water and create steam, which drives turbines connected to generators that produce electricity. The steam is then condensed back into water and recycled in a closed-loop system.
Geothermal energy is generated by using the earth's heat. This renewable energy source involves tapping into heat stored beneath the Earth's surface to produce electricity or provide heating and cooling for buildings.
in the uk electricity is generated at ?
the asia's largest producer of nuclear generated electricity is Japan.
yes
it canotyes it can
yes
They use a generator to turn it into Electricity
No because the electricity fairy is sleeping at night.
Hyro-electricity is the same as any other electricity. the Hydro- prefix merely denotes how the electricity was generated, in this case it was generated at a hydro-electric plant which uses the potential energy of elevated water to generate electricity.
Becuase static electricity is generated by rubbing or by friction.
use electricity generators which generate electricity from candle energy
The amount of CO2 generated from electricity (kWh) is dependant upon the way the electricity is generated. Burning a barrel of oil to produce electricity yields far more CO2 than generating the same amount of electricity from wind or water. One should contact their electricity provider to get a break-down of how the electricity is generated.
