Discovery of electricity; How electricity discovered

Now days electricity is backbone of everyone life. It seems life is electricity. There was most often curiosity in every human being that who discovered electricity and when. Let’s read article below to know how electricity was discovered.
As everyone knows electricity is nothing but source of energy. Electricity is not invented as it is form of energy and was always present. It is only discovered and most people think that this is discovered by Benjamin Franklin but his experiments helps in getting a connection between lightning and electricity.

Way back in 600 BC ancient Greeks discovered that “When we rubbing fur on amber it caused attraction between the two” thus we can say that they have discovered static electricity.
There are so many discoveries has been made upto 17th century such as:-
1.    Invention of electrostatic generator
2.    Difference between positive and negative currents
3.    Classification of materials as conductors or insulators.
William Gilbert:-
In 1600 year, William Gilbert describe that when force which some substances exert when rubbed against each other is known as”electicus”.

Thomas Browne:-
Thomas Browne describe the word “electricity” In his several books. His investihgations were based on William Gilbert work.
Ben Franklin:-
A well-known experiment was done by Ben Franklin, In 1752, with a kite, a key, and a storm. Electricity from the storm clouds transferred to the kite key and electricity flowed down the string and gave him a shock. Luckily he get escaped unhurt so by this he proved his idea.
Through this experiment he proved that lightning and electric sparks are same thing.
Alessandro Volta
Volta was an Italian physicist. He discovered that a particular chemical reaction produces electricity. In 1800 he constructed the voltaic pile, which was an electric battery, that produced a steady electric current also called as DC battery. Volta also created the first transmission of electricity by linking positively-charged and negatively-charged connectors and driving an electrical charge, or voltage, through them.
Michael Faraday:-
Everyone know Faraday efforts for electricity generation. In year 1831 Michael Faraday make electricity use viable by creating the electric dynamo . Faraday’s uses a magnet that was moved inside a coil of copper wire, creating a tiny electric current that flowed through the wire.
Faraday also stated Law of electromagnetic Induction for production of electricity which is basis of today electricity generation.

In 1878 American Thomas Edison and British scientist Joseph Swan invented the incandescent filament light bulb in their respective countries.
In 1882 Edison used his direct-current system (DC) to provide power to illuminate the first New York electric street lamp.
In Late 1800’s and early 1900’s inventor Nikola Tesla became an important contributor to the birth of commercial electricity. He also worked with Edison. Tesla had many revolutionary developments in
(i)            Electromagnetism,
(ii)          Invention of radio
(iii)         AC motors
(iv)         Polyphase distribution system.
There are many other inventors which played an important part in field of electricity.
(a)  James Watt
(b)  Andre Ampere
(c)  George Ohm.
So it is unfair to name a single man for discoveries and inventions in field of electricity. They have all made great contributions in field of electricity through which we have such a great electricity system.
In 1936 it has been found that ancient  peoples have also experimented with electricity, too. In 1936, a clay pot was discovered that suggests that the first batteries may have been invented over 2,000 years ago. The clay pot contained copperplates, tin alloy, and an iron rod.

It could have been used to create an electric current by filling it with an acidic solution, like vinegar. No one knows what the device was used for, but it sheds some light on the fact that people may have been learning about electricity long before Benjamin Franklin!
