How is electricity formed? How electricity is generated

To put it simply, electricity is a substance that cannot be seen or touched, but it also exists objectively.

Electricity is a form of energy, including negative and positive electricity, they are composed of electrons and protons, respectively, and may also be composed of electrons and positrons, usually measured in electrostatic units (such as electrostatic coulombs) or electromagnetic units (such as coulombs), its existence can be observed from the attraction and repulsion of tribogenic objects, and it can also be observed in certain natural phenomena (such as lightning or the Northern Lights), and is usually utilized in the form of electric current.

Electricity is a natural phenomenon, and it is one of the basic interactions in nature. In China, the ancients believed that the phenomenon of electricity was generated by the stimulation of yin and yang. "Vocabulary" has "thunder from the back, electricity from the shen."

Yin and yang become thunder with thinness, and electricity is electricity with catharsis." In the ancient book Lunheng (about the first century A.D., that is, the Eastern Han Dynasty), there is a record of static electricity, when amber or tortoiseshell can attract small and light objects after rubbing, and the phenomenon of electricity caused by friction of silk is also described, but ancient China did not know much about electricity. In the century, the West began to explore various phenomena of electricity.

Benjamin Franklin first proposed the concept of electric current, and in a kite experiment, he put a metal wire on a kite tied to it into the clouds, and the rain-soaked metal wire led the lightning in the air between his finger and the key, proving that lightning in the air is the same thing as electricity on the ground. Soon after, a great scientist, Faraday, built the world's first electromagnetic induction generator and became a pioneer in the electric age of mankind. The discovery and widespread use of electricity is the result of the second scientific and technological revolution, and at the same time, it is also the capital of the third scientific and technological revolution.

Its discovery has brought great convenience to human life. If there were no electricity in the world, we would spend every night in darkness; If there is no electricity in the world, all the machines in the factory will stop production; If there were no electricity in the world, all electrical appliances would not exist. Our lives are inseparable from electricity, but it is also detrimental to people and the environment; For example, electric shock, electrical radiation, etc.

If we can regulate the use of electricity reasonably, then electricity will serve us better.

When I was in middle school, I learned that the wire can generate an induced current as long as it cuts the magnetic field lines, and the generator is a special device that continuously cuts the magnetic field lines, so as to continuously obtain the sense of generating current.

To put it simply, the directional movement of positive and negative charges forms an electric current.

Electricity is generated in this way (using magnets and coils), and the electricity used today can be broadly divided into electricity generated by generators and electricity (such as batteries) that converts chemical energy into electricity. In addition, other methods of generating electricity are being developed, such as electricity generated by sunlight. Of course, the electricity used in the home is generated by the generator.

Now, let's take a look at the principle of power generation! To generate electricity, you need magnets and coils that generate electricity. Magnets have a magnetic force that attracts metals such as iron, and the range of this force is called the magnetic field.

When the coil is moved in this magnetic field, electricity is generated in the coil. However, in a strong magnetic field, electricity cannot be generated without being able to move the coil (without making a change in the magnetic force). In other words, the change in magnetic force causes the coil to generate electricity.

This principle is called electromagnetic induction, and the current generated is called induced current. As the magnet approaches the coil, the current flows towards the coil in the direction of the arrow. Conversely, if the magnet moves away from the coil, the current flows in the opposite direction of the arrow.

Of course, if you don't move the magnet, the magnetic field will not change, and electricity will not be generated. This electromagnetic induction can also be used in a simple generator of a bicycle. If a generator is installed on the tires of a bicycle, the magnets inside the generator will rotate with the help of the rotation of the tires.

In this case, the strength of the magnetic field near the coil changes, and an induced current flows to the coil. This is how electricity is generated, which turns on the lights of the bike. Closely related to power generation is the generator of the power company.

Hydroelectric power generation uses water power to rotate the propeller mounted on the generator to replace the rotation of bicycle tires, so that the magnet rotates and generates electricity. Thermal power generation or nuclear power generation is first produced by a boiler or atomic furnace to produce high temperatures, and then the heat is used to evaporate water to produce vapors, which are strongly sprayed at the turbines installed on the generator to rotate the generator and generate electricity.

The generation of electricity is actually electronic, moving in a directional way.

Matter is made up of molecules, and molecules are made up of atoms, which are composed of negatively charged electrons and positively charged protons. Under normal conditions, the number of protons and the number of electrons of an atom are the same, and they are in equilibrium, so they are not charged externally. However, the electrons surround the nucleus, and as soon as they are separated from the orbit by external force, they leave the original atom and invade other atoms B, atom A has a positive charge phenomenon due to the lack of electron number, which is called cation, and atom B is negatively charged due to the increase in the number of electrons, which is called anion.

The cause of the unbalanced electron distribution is that the electrons are deorbited by an external force, which includes various energies (such as kinetic energy, potential energy, thermal energy, chemical energy, ......etc.).In daily life, static electricity can be generated when two objects of different materials come into contact and then separate. When two different objects come into contact with each other, one object loses some charge, such as electrons are transferred to another object to make it positively charged, and the other body gets some remaining electrons and becomes negatively charged. If the charge is difficult to neutralize during the separation process, the charge will accumulate and the object will be electrostatically charged.

Whereas, electricity can also be divided into alternating current and direct current. Their distinction is mainly in the direction of the current.

The electricity underneath is electron induction, phenomena, and electricity generates magnetism.

Electricity is a property of the repulsive force and attraction that arises between subatomic particles like electrons and protons. It is one of the four basic interactions in nature. There are two kinds of electronic motion phenomena:

We say that an atom that lacks electrons is said to be positively charged, and an atom that has excess electrons is said to be negatively charged.

Electricity is a general term that is a physical phenomenon produced by a stationary or moving electric charge.

Charge: The contrinsic properties of certain subatomic particles. This property determines their electromagnetic interaction with each other. Charged matter is affected by an external electromagnetic field, and at the same time, an electromagnetic field is also generated.

Electric Current: The directional movement of charged particles, usually measured in amperes.

Electric field: An effect produced by an electric charge. Other nearby charges will feel the electric field force due to this effect.

Electric potential: The potential energy possessed by a unit charge at a certain point in an electrostatic field, usually measured in volts.

Electromagnetic action: A fundamental interaction between an electromagnetic field and an electric charge at rest or in motion.

Most of China's coal power generation, the simple point is to use coal, burn boilers, produce steam, push generators, is the conductor and then cut magnetic induction wires, generate electricity, high temperature and high pressure gas is only used as a drive, the efficiency is very low A lot of coal is burned in vain, and it has caused a lot of pollution, I feel that in China, electric energy is not a clean energy, because most of the electric energy still comes from polluting coal combustion...

However, there are also hydropower now, such as the Three Gorges, which use water to drive generators, and the energy is relatively clean, but it may cause greater damage to the ecology.

Nuclear energy, the use of the decay of emitting elements, recently heard more Haha, this because it is enriched in some kinds of radioactive elements in nature, so the energy per unit mass is very high, and then it is also the use of a large amount of heat released in the decay process to vaporize water, but also the use of high temperature and high pressure water vapor to drive the generator

Others, such as wind energy and solar energy, are relatively small in scale and have not reached the level of industrialization, and are now being studied.

An electric current is generated when a resistive conductor is closed and cuts in a magnetic field.

Friction produces positive and negative charges, and the directional motion of the charges forms an electric current.

The first triboelectric was discovered by scientists, and after one scientist after another, it has been studied by scientists to today's hydropower stations, nuclear power plants, wind power stations, and so on.

The generation of electricity is simply a group of coils that rotate in a magnetic field through external power, and the electric potential is generated by cutting the magnetic field lines through the rotation of the coils, so that there is electricity.

Electricity is a physical phenomenon produced by a stationary or moving electric charge.

In real life, the mechanism of electricity gives many well-known effects, such as lightning, triboelectric induction, electrostatic induction, electromagnetic induction, and so on.

According to ancient Egyptian books written in 2750 BC, these fish were known as the "thunder messengers of the Nile" and were the protectors of all other fish. It was about 2,500 years later that the Greeks, Romans, Arab naturalists and Arab physicians began to write about the fish.

Electricity is a natural phenomenon, and it is one of the 4 basic interactions in nature. In China, the ancients believed that the phenomenon of electricity was created by the combination of yin and yang.

Electricity is a natural phenomenon. Electricity is a property that produces repulsion and attraction between subatomic particles like electrons and protons. It is one of the four basic interactions in nature.

There are two kinds of electricity or charges: we call one positive and the other negative. Through experiments, we have found that charged objects repel the same sex and attract the opposite sex, and the attraction or repulsion follows Coulomb's law.

Glass rods rubbed against silk have a positive charge, and rubber rods rubbed against fur have a negative charge.

The unit of charge in the SI system of units is the coulomb. 1 coulomb = 1 ampere·second.

If a steady current of 1 ampere is carried in the wire, the amount of electricity passing through the cross-sectional area of the wire in 1 second is 1 coulomb.

Coulombs are not an International Standard Unit, but an International Standard Derivation Unit. 1 coulomb = 1 ampere·second. The amount of negative charge carried by an electron e coulomb, also the current and the circuit.

Under the action of the power supply, the charged particles will move directionally, and the positive charge will move to the negative pole of the power supply, and the negative charge will move to the positive pole of the power supply. The directional movement of charged particles is the current current, and the direction in which the positive charge moves is generally the positive direction of the current. A current in which the direction and magnitude of an electric current do not change with time is called direct current, and a current in which the magnitude and direction of an electric current periodically change over time is called alternating current.

The magnitude of the current is called the current intensity, and the current intensity is simply called the current. The common unit of electric current is ampere(a) or milliampere oooma.

The path through which the current flows is the circuit. In a closed circuit, the transfer and conversion of electrical energy is realized. The circuit consists of a power supply, connecting wires, switching appliances, loads and other auxiliary equipment.

The power supply is a device that provides electrical energy, and the function of the power supply is to convert non-electric energy into electrical energy, such as a battery converts chemical energy into electrical energy, and a generator converts mechanical energy into electrical energy. Dry batteries, accumulators, generators, etc. are the most commonly used power sources. A load is a device that consumes electrical energy in a circuit, and the function of a load is to convert electrical energy into other forms of energy.

For example, electric furnaces convert electrical energy into thermal energy, and electric motors convert electrical energy into mechanical energy. Lighting appliances, household appliances, machine tools, etc. are the most common loads. Switching appliances are load control equipment, such as knife switches, circuit breakers, electromagnetic switches, pressure reducing starters, etc.

Auxiliary equipment includes various relays, fuses and measuring instruments. Auxiliary equipment is used to control, distribute, protect and measure circuits. Connecting wires connect power supplies, loads, and other equipment into a closed loop, and the connecting wires are used to transmit electrical energy or telecommunication signals.

That is, 1 coulomb is equivalent to the total amount of charge carried by an electron.

The essence of electricity is: matter is made up of molecules, molecules are made up of atoms, and atoms are made up of atomic nuclei and electrons revolving around the nucleus. The nucleus of an atom has a positive charge and the electrons have a negative charge.

That's where electricity comes in. The use of mechanical energy or chemical energy or radiant energy (nuclear radiation, solar energy) to generate electric potential, this electric potential is the electric potential energy, which makes the charge flow from high potential to low electric potential, and in the closed circuit it produces a moving charge, that is, current.

Matter is composed of atomic electrons and neutrons, and under certain circumstances, the electrons in the nucleus will gain or lose or shift, forming an electric potential, that is, voltage, and when the electrons move, an electric current is formed.
