![]() He bought a number of patents related to electric lighting and began experiments to develop a practical, long-lasting light bulb.ġ879 After many experiments, Thomas Edison invented an incandescent light bulb that could be used for about 40 hours without burning out. Thomas Edison founded the Edison Electric Light Co. His lightbulb burned out quickly.Ĭharles Brush developed an arc lamp that could be powered by a generator. Maxwell’s four laws of electrodynamics (“Maxwell’s Equations”) eventually led to electric power, radios, and television.ġ876 Charles Brush invented the “open coil” dynamo (or generator) that could produce a study current of electricity.ġ878 Joseph Swan, and Englishman, invented the first incandescent lightbulb (also called an “electric lamp”). Maxwell created a new era of physics when he unified magnetism, electricity and light. A unit of thermal energy, the Joule, was named after him.ġ844 Samuel Morse invented the electric telegraph, a machine that could send messages long distances across wire.ġ860’s Mathematical theory of electromagnetic fields published. Because this devise used a coil of wire, it produced spikes of electric current followed by no current.ġ835 Joseph Henry invented the electrical relay, used to send electrical currents long distances.ġ837 Thomas Davenport invented the electric motor, an invention that is used in most electrical appliances today.ġ839 Sir William Robert Grove developed the first fuel cell, a device that produces electrical energy by combining hydrogen and oxygen.ġ841 James Prescott Joule showed that energy is conserved in electrical circuits involving current flow, thermal heating, and chemical transformations. Pixxi’s dynamo used a crank to rotate a magnet around a a piece of iron wrapped with wire. ![]() He also described an electric motor.ġ832 Using Faraday’s principles, Hippolyte Pixii built the first “dynamo,” an electric generator capable of delivering power for industry. Joseph Henry separately discovered the principle of electromagnetic induction but didn’t publish his work. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. 1826 Georg Ohm defined the relationship between power, voltage, current and resistance in “Ohms Law.”ġ831 Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field.
