History Of Electricity


The early history of electricity was discovered by a Greek scholar named Thales, a phenomenon notify the yellow when rubbed - rub the fur will be interesting as a phenomenon of electricity. Then after many - years after Thales ideas put forward, and then reappeared opinions - opinions and new theories regarding electricity as researched and presented by William Gilbert, Joseph priestley, Charles de Coulomb, AmpereMichael Farraday, Oersted, etc..

information about the history of the inventor of electricity is presented in bentu panel and supported by the audio device that presents visual clone of experiments - experiments that have been done by scientists.

Ben Franklin
Many people think Benjamin Franklin discovered electricity famous kite experiment in 1752, but
electricity was not discovered all at once. At first, the electricity associated with light.
People want a cheap and safe way to light their homes, and scientists thought possible electrical path.

Battery

Learning how to produce and use electricity is not easy. For a long time there
no reliable source of electricity for the experiment. Finally, in 1800, Alessandro Volta, an Italian scientist, makes a major discovery. he's soaked
paper in salt water, zinc and copper are placed on opposite sides of the paper, and observe the chemical reaction produces an electric current. Volta had
created the first electric cell. By connecting many of these cells together, Volta was able to "current string" and make batteries. It is in honor of Volta that we measured in volt battery. Finally, sources of safe and reliable electricity is available, making it easier for scientists to study electricity.

In the case of electricity, there are many leaders who have participated. Call it de Coulomb, Alessandro Volta, Hans C. Cersted, and Andre Marie Ampere. They are considered "magnate" best in the field of electricity. However, from all that, one should not forget the name of a very meritorious and is known as a pioneer in electricity and magnetism. He was Michael Faraday, a British scientist.

Michael Faraday was born on 22 September 1791 in Newington Butts, England. His parents belong to poor families. His father was a blacksmith who only have to feed ten children. No wonder if his father was unable to pay for her children's school was no exception with Faraday. To help the family economy, at the age of 14 years Faraday worked as a bookbinder and seller of books. In between jobs he use to read different types of books, especially science, physics, and chemistry.

When she stepped 20 years, he attended lectures given by renowned British scientist. One is Sir Humphry Davy, a chemist who is also head of the Royal Institution laboratory. During the lecture, Faraday notes carefully and neatly copy it back what he heard. Then, the file notes that he sent to the Humphry Davy with a job application. Apparently the professor interested and raised Faraday as a laboratory assistant at the Royal Institution in London. At the age of 21 years.

Under the guidance of Davy, Faraday showed rapid progress. Initially, it only works as a bottle washer. But, thanks to his perseverance in learning, only in a relatively short time, he can make new discoveries on the results of his own creation, which found two compounds klorokarbon and succeeded in liquefying chlorine and other gases. Thank you also intelligence, Faraday may be associated with renowned experts, such as Andre Marie Ampere. In addition, he also got a chance toured Europe with Davy. On that occasion, Faraday began to build practical and theoretical knowledge.

Davy had a major influence in the thinking and has led Faraday Faraday on his findings. Faraday first important discovery in the field of electricity occurred in 1821. Oersted two years earlier had found that the magnetic needle compass can be shifted if the normal electrical current flowed in the wire are not far apart. From these findings, Faraday concluded that, if the magnet diketatkan, just moving the wires. Working on the basis of these allegations, he managed to make a clear scheme where the wire will constantly rotating magnet adjacent to all electrical power is applied to the wire.

Indeed, in this case the Faraday had discovered the first electric motor, a first scheme uses an electric current to create something moving objects. No matter how primitive, Faraday's discovery of an "ancestor" of all electric motors used today's world. Since the first discovery in 1821, the scientist Michael Faraday This autodidact his name became famous. Inventions regarded as paving the way in the field of electricity.
Faraday's law

In experiments done in 1831, he found that when a magnet through a wire, current will flow in the wire, while the magnet moves. This is called "electromagnetic influences" and this is called a "Faraday's law". These findings are considered as a monumental discovery. Why? First, the "Faraday's law" has significance in relation to our theoretical understanding of electromagnetic. Second, can be used as an electromagnetic drive continuous flow of electricity as used by Faraday in the manufacture of the first electric dynamo.

With a variety of findings, including Faraday's no exaggeration if one of the figures who have contributed most to mankind. He was a modest, an inventor who started learning autodidact. Simplicity he showed when he rejected been knighted and also refused to be president of the British Royal Society. Due to health problems, Michael Faraday stop working. But, he continued as a professor until 1861. He died on August 25, 1867 and was buried near the town of London, England.


Thomas Edison
n 1879, Thomas Edison
focused on creating a
Light the lamp, which
will last a long time before
burning. The problem is
find strong material for
filament, a small wire
inside the bulb that does
electricity. Eventually, Edison used
ordinary cotton thread
been soaked in carbon.
These filaments do not burn at
all it is bulb;
that is, it shines.

The next challenge is to develop systems that can power
provide people with a practical source of energy to power these new
lights. Edison wanted a way to make practical electric and
cheap. He designed and built the first power plant
capable of generating electricity and took it to people's homes.
Edison's Pearl Street Power Station began a generator which in
September 4, 1882, in New York City. About 85 customers under
Manhattan received enough power to light 5,000. Her
electricity customers pay a lot for them, though. In today's dollars,
electricity costs $ 5.00 per kilowatt-hour! Currently, the cost of electricity
about 12 cents per kilowatt-hour for residential customers, and
about 7 cents per kilowatt-hour for the industry.

AC / DC
The turning point of the electric age came a few years later with
development of AC (alternating current) power systems. with
alternating current, the power plant can carry a lot of electricity
further than before. In 1895, George Westinghouse opened the first
The main power plant at Niagara Falls using alternating current. while
Edison's DC (direct current) power plants can only carry
within one square mile of his Pearl Street Power Station, Niagara
Plants falling capable of transporting electricity over 200 miles!
Electricity does not have an easy start. Many people
pleased with all the new discoveries, but some people fear
electricity and alert brought to their home. many social
critics today see power as an end to a simple, less hectic
life. Poets commented that electric lights are less romantic than
gas lamps. Maybe they are right, but the new electric age can
not dim.
In 1920, only two percent of the energy in the U.S. is used to make
electricity. Today, about 41 percent of the energy used to make
electricity. As we use technology grow, that number will continue to
increased.
