Dr. William Gilbert studies the reaction of amber and magnets, first recording the term “electric” in a report on the theory of magnetism.
I think it is important because he was a first person to use the "electric" term to explein his theory. -

Benjamin Franklin tests his theory, fastening an iron spike to a silk kite and holding the end of the kite string by an iron key during a thunderstorm.
It is important because after of this discovery they were invented the lighting rod to protect the persons to the electricity from lighting. -

Scotsman James Watt invents the steam condensing engine, which proves crucial to large-scale generation of electricity.
The steam condensing engine let the society consume large amount of electricity and do things that it was impossible to do before because of the limited energy. -
Hans Christian Oersted of Denmark holds a magnetic compass near a current-carrying wire, discovering electromagnetism.
This discovery was crucial to confirm the relationship of electricity and magnetism. -
Alexander Graham Bell patents the telephone, which transmits speech over electric wires.
I think it is an important fact because telephone saves us a lot of time to speak with another person wherever they are. -
Frank Sprague demonstrates the first practical electric motor for use in locomotives.
This is an important invention because the electric motor used in locomotives let people move easier from one place to another. -
Nikola Tesla , introduces the alternating current generator, allowing electricity to be distributed longer distances than the two miles possible with direct current generators.
I think it is one of the most important inventions because after that we can move the electricity from place far from the civilization. -
American Lee De Forest, invents a vacuum tube that amplifies radio signals, making the development of radio and television communication possible.
It is an important invention because it let the society be informed of the last news of any topic and from anywhere. -
Electronic computers invented. Electric freezers, frying pans, portable mixers and improved air conditioners introduced.
I think it is important because this kind of invents let future generations improve their life conditions. These electrical appliance makes people live better. -
A nuclear reactor built at Arco, Idaho, powers a generator, producing the first electricity generated by atomic energy.
Nuclear reactors produce the major part of the energy that nowadays we use, although it is contaminant and dangerous.
