Michael Faraday (England) discovered the principle of electro-magnetic rotation that would later be the key to developing the electric motoGeorg Ohm (Germany) defined the relationship between power, voltage, current and resistance in Ohms Law.Using his invention the induction ring, Michael Faraday proved that electricity can be induced by changes in a electromagnetic field. Faraday's experiments on how electric current works led to the understanding of electrical transformers and motors.
later, Joseph Henry separately discovered the principle of electromagnetic induction but didn't publish his work. He also described an electric motor.ames Prescott Joule shows that energy is conserved in electrical circuits involving current flow, thermal heating, and chemical transformations. A unit of thermal energy, the Joule, was named after him.Samuel Morse invented the electric telegraph, a machine that sendsmessages long distances across wires.Charles Brush invented the open coil dynamo/ generator that could produce a steady current of electricity.Joseph Swan invented the first incandescent lightbulb . His lightbulb burned out quickly.
Charles Brush developed an arc lamp that could be powered by a generator.
Thomas Edison founded the Edison Electric Light Co. in New York City. He bought a number of patents related to electric lighting and began experiments to develop a practical, long-lasting light bulb.Thomas Edison opened the Pearl Street power station in New York City. The power station was one of the world's first central electric power plants and could power 5,000 lights. It used a direct current power system, unlike the power systems that we use today which use alternating current.Nikola Tesla invented the Tesla coil, a transformer that changed electricity from low voltage to high voltage, making it easier to transport over long distances.Nikola Tesla invented the electric alternator for producing alternating current. Until this time, electricity had been generated using direct current from batteries.
Sir Charles Algernon Parsons invented a steam turbine generator, capable of generating huge amounts of electricity.William Stanley, Jr. developed the induction coil transformer and an alternating current electric system.Nikola Tesla demonstrated the first polyphase alternating current electrical system. His AC system included all units needed for electricity production and use: generator, transformers, transmission system, motor (used in appliances) and lights. George Westinghouse, the head of Westinghouse Electric Company, bought the patent rights to the AC system.
Charles Brush was the first to use a large windmill to generate electricity. He used the windmill to charge batteries in the cellar of his home in Cleveland, Perioden
a 9 year time period were inventors like Hippolyte Pixii, Joseph Henry, Thomas Davenport and Sir William Robert Grove created usfeul and relevant items like the dynamo, electrical relay, electric motor and the first fuel cell.The mathematical theory of electromagnetic fields was published. J.C. Maxwell. He created a new era of physics when he unified magnetism, electricity, and light. Maxwell's four laws of electrodynamics eventually led to electric power, radios, and television.The Niagara Falls hydropower station opened. It originally provided electricity to the local area. One year later, when a new alternating current powerline was opened, electric power from Niagara Falls was sent to customers over 20 miles away in Buffalo, New York.
