Electricity Electricity is one of the inventions that has completely changed the course of life. It has become the primary source of energy in our daily life and the main operator of all the devices and machines that we can no longer afford. Electricity is also becoming increasingly sophisticated as many machines that operated in other ways Like fossil fuels, it is slowly turning into electricity, for example, cars. The history of electricity Although people have noticed since a number of electrical phenomena such as lightning, static electricity, etc., mankind did not know the use of electricity and what it is and only think about its exploitation in the nineteenth century and after nearly fifty years of the famous Benjamin Franklin experiment, which connected a key to a kite during a thunderstorm , In which he proved that lightning and static electricity are the same thing. In 1800, the Italian scientist Alessandro Volta invented the battery when copper and zinc were placed on opposite sides of a sheet of salt-watered paper, creating an electric current. In honor of this world, the voltage unit was named volt. This gave the scientists a safe and continuous source of electricity , After which invented the English world Varaday-born electricity using magnets, a principle that most of the generators in the current era are using. The world that started using electricity in practical terms was Thomas Addison inventing the light bulb and construction of the first power station in London able to transmit electricity to people and across the streets, and since that time there has been a very large revolution in the field of electricity and electrical and electronic devices on which the world depends on the era Present. Electricity generation Coal was the first means to generate electricity in large quantities sufficient for the needs of cities, factories, etc. But as a result of the increasing reliance on electricity and the difficulty of relying on coal to generate electricity as a result of the increase in demand has been invented many different ways to generate electricity using other types Of energy, but this does not deny that coal is still one of the first sources of power generation and the most widespread. In addition to coal, other fossil fuels, such as natural gas and oil, are also very reliable for generating electricity. Fossil fuel is the primary source of electricity generation, and other sources that rely on electricity are nuclear power. Modern methods of generating electricity, but fossil fuels and nuclear energy are not a safe source of electricity, so the world is now gradually turning to electricity generation using alternative and renewable sources, mainly solar, wind and water. These sources are the future sources of power generation. Provide a sustainable source of energy and also protect the environment from pollution.
