Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. ... Electricity is not a human invention
Alessandro Giuseppe Antonio Anastasio Volta (UK: / ˈ v ɒ l t ə /, US: / ˈ v oʊ l t ə /; Italian: [alesˈsandro ˈvɔlta]; 18 February 1745 – 5 March 1827) was an Italian physicist and chemist who was a pioneer of electricity and power, [1] [2] [3] and is credited as the inventor of the electric battery and the discoverer of methane.
English inventor Francis Ronalds built the first working electric telegraph. 1820: Danish physicist Hans Christian Ørsted accidentally discovered that an electric field creates a magnetic field. 1820: One week after Ørsted's discovery, French physicist André-Marie Ampère published his law. He also proposed the right-hand screw rule. 1821
A simple electromagnet, consisting of an insulated wire wound around an iron core. An electric current passing through the wire creates a Magnetic field, with a north pole at one end and a south pole at the other. The first application of electricity that was put to practical use was electromagnetism. [18]
Much of early electricity was direct current, which could not easily be increased or decreased in voltage either for long-distance transmission or for sharing a common line to be used with multiple types of electric devices. Companies simply ran different lines for the different classes of loads their inventions required.
Back in the early 1900s, genius inventor Nikola Tesla envisioned a system that would transmit electricity wirelessly through the air … free for anyone to use. He did more than just envision it.
Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. [1] [2] [3] He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. [4]
