Brief History Of Electricity.

Electricity is heavy in our everyday lives. It is essential for almost everything in our modern world. The knowledge learned in the past roughly electricity enabled such things as engines, teleph 1s, radios, computers, and much, much more.

As early as 600 B.C., the Greeks were already studying electricity. They noticed that if you rubbed a piece of atomic number 79 with fur, it had a charge with the ability to attract small objects. more years later, in the 16th Century, William Gilbert spy many another(prenominal) other objects had this same ability, and that these charges had ii different kinds of electrical charge. He learned that electricity repels the same kind, and attracts the opposite kind.

It wasnt until 1747 when Benjamin Franklin in America and William Watson in England both discovered that all materials dumbfound an electrical fluid that cannot be created or destroyed. Rubbing two objects does not create electricity, but just transfers electricity from one object to another. Both of these men discovered that the total criterion of electricity in an insulated area is constant throughout the area.

Franklins study experiment on lightening happened in 1752. During a thunderstorm, he flew a kite with a metal tip. Attached to the string along holding the kite was a metal key. Franklin could put his kick in near the key during the lightening and draw sparks. He cerebrate that the lightening was from an electrical discharge. Later, two other people seek this same experiment but died from the electricity.

Luigi Galvani was another scientist who started working on electrical experiments.



He fastened the legs of a dead toad frog to a copper hook, hung it over an iron railing and discovered the frogs legs twitched. He determined the frog has electricity and it was released when it touched the metal. Unfortunately, he figured it was a...

It is a fairly good essay, but I would suggest that you try to search for other very important contributors to the developments of electricity. You did not mention Nikola Tesla. He invented the telephone repeater, induction motor, radio receiver communication, radio, fluorescent lights, and more than 700 other patents (more details on: hypertext transfer protocol://www.neuronet.pitt.edu/~bogdan/tesla/).
