Why does the world have electricity, and where does the world s electricity come from?

Electricity is a natural phenomenon and is a type of energy. Lightning in nature is a phenomenon of electricity. 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 electricity or charges: we call one positive electricity and the other negative electricity.

Electricity is a general term that encompasses many phenomena that arise due to the presence or movement of electric charges. There are many phenomena that are easy to observe, such as lightning, static electricity, etc., and some relatively unfamiliar concepts, such as electromagnetic fields, electromagnetic induction, and so on.

Electricity also has many uses, such as electric lights, etc., everyone knows. Therefore, electricity represents the spirit of human beings who do not admit defeat, a kind of progress of human beings!

You wouldn't be here without electricity, and you know that electricity, like water, is an essential thing in modern society.

Because he is a thing that coexists with the world, bioelectricity, thunder, and static electricity

1. The conventional hydropower station intercepts the water to the reservoir or intercepts the river to form a dam, and the drop of the concentrated water flow (kinetic energy and gravitational potential energy) forms the head after gathering, regulates the flow of the water flow, and impacts the water turbine, drives the generator, converts the concentrated water energy into electrical energy, and then feeds the chain oak electric energy into the power grid through transformers, switch stations and transmission lines.

2. Electricity is a natural phenomenon that refers to the phenomenon caused by the movement of electric charges. Greenhouse lightning in nature is a phenomenon of electricity. Electricity, for example, 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 phenomena of electron motion: we say that an atom that lacks electrons is positively charged, and an atom that has excess electrons is said to be negatively charged.

Electricity originally existed in nature, but people gradually studied it and were finally able to produce it themselves. Electricity is generated by electromagnetic induction generators, using magnets and coils, which were invented by Faraday Research. 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 produce 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. Oh.

Zero-based learning of electronics, starting from the initial starting point "atom", from easy to difficult, step by step, take you into the wonderful world of electricity!

The discovery and application of electricity, so that human beings from the age of steam into a new era, the wide application of electricity, make people's lives more convenient, make our lives more convenient, and the magic of electricity lies in this, if there is no electricity, the world will fall into chaos.

Electricity is a general term that is a physical phenomenon produced by a stationary or moving electric charge. In nature, the mechanism of electricity gives many well-known effects, such as lightning, triboelectric induction, electrostatic induction, electromagnetic induction, and so on. For a long time, there were many warlocks who devoted themselves to the study of the phenomenon of electricity.

However, the results are really lackluster, very few. It was not until the seventeenth and eighteenth centuries that there were some important developments and breakthroughs in science. At that time, scientists did not find any practical use for electricity.

This was not until the end of the 19th century, when advances in electrical engineering brought electricity into industry and households. In this era of electrical research and development, the rapid and continuous development has brought indescribable and unimaginable changes to industry and society.

Man's demand for electricity is exaggerated, and its role is no less than that of oxygen in the human world. Modern electricity due to the decreasing conventional energy and there is a crisis, countries around the world are taking new energy as the direction of development, the main promotion of wind energy, solar energy, geothermal energy, etc., with the progress of technology, the conventional energy consumption of electricity will be replaced! The living environment of human beings will be improved.

The discovery and wide application of electric power has made earth-shaking changes in people's lives, and people's lives are becoming more and more convenient, electric energy is an extremely important material for the development of human society, so that human power has grown wings, and human information tentacles continue to extend. The impact of electricity on human life is twofold: the acquisition, transformation and transmission of energy, and the basis of electronic information technology.

The discovery of electricity can be said to be a revolution in human history, and the kinetic energy generated by it is continuously released every day, and without electricity, human civilization would still be exploring in the dark.

In a world without electricity, there will be no development of science and technology, everything will return to the most primitive society, and electronic products such as mobile phones and computers will become bricks.

The world without electricity will become a form of social activity in the period of feudal monarchy, and although it is supported by steam power, the productivity will be low, and the development of human society will be very slow.

Without electricity, there would not be so many colorful lights at night, and life would be extremely inconvenient. There will not be so many electrical appliances produced now, which shows how important electricity is to us.

Zero-based learning of electronics, starting from the initial starting point "atom", from easy to difficult, step by step, take you into the wonderful world of electricity!

It was found that electricity is closely related to people's lives and is inseparable from it. Therefore, we should learn to cherish all things in the world. 1. If the electricity is out, there will be no TV programs, and we can't watch TV without electricity, and we can't enjoy wonderful TV programs.

2. The radio is also unusable because of the lack of electricity. 3. The rice cooker can't be used, the induction cooker can't be used, and the electric kettle can't be used. 4. If the phone can't be charged, it can't be used.

5. The food in the refrigerator will thaw and the food will rot. 6. The washing machine cannot be used, although the laundry can be done by hand. 7. People who live on the upper floors can't use the elevator anymore and have to climb the stairs.

8. The plane can't take off, the train can't run, and the subway can't run! If there are no traffic lights on the road, there will be traffic accidents and traffic paralysis. 9. The hospital can't do surgery, there is no electricity, doctors can't use shadowless lamps to do surgery, and many patients will not get effective **!

10. The factory will stop working, and if there is no electricity, the factory machines will stop rotating! What kind of food, clothing, housing and transportation can people leave the factory to manufacture? 11. In the dark night, the ancient oil lamp can no longer meet the needs of modern people, and electricity has become an indispensable thing in modern life.

12. Computers can't be used, and the Internet, switches, and servers will be paralyzed! 13. Without electricity, we can only rely on the faint moonlight to grope our way outside, and there is a danger ......of falling if we are not carefulPeople who work night shifts can't work. 14. Without electricity, there is no way to desalinate seawater, there is no tap water, and there is no way to treat sewage, and the problem will be very serious!

15. Without electricity, it will be difficult for companies, schools, and institutions to operate normally, especially in today's highly information-based world! 16. All tourist attractions will not be able to operate normally. 17. No communication tools can be used.

18. The quality of life will be greatly reduced, diseases may run rampant, and various social problems will become more and more serious! 19. Summer without air conditioning will be very uncomfortable. 20. Without QQ and MSN, there is nothing, so what is it good for?
