Francis Hawks
The English philosopher Francis Hawks discovered, for example, in the early 1700s, that a spinning a glass globe produced electricity, this creating one of the first electrical generators. -
Stephen Gray y Granville
Weller discovered that electricity could be transmitted over long distances by contact. This was an important first step towards researching currents, but above all it was an excuse for fully ethical scientific demonstrations. -
Ben Franklin
He developed the lightning rod -
Voltaic Cell
Alessandro Volta created the first practical method of generating electricity, the first battery known as a voltaic cell -
Electric Charge and The Magnetic Attraction
Hans Christian Oersted discovered that the electrical charge and the magnetic attraction of the compass were linked. across wires, this became known as erst Ed's law -
The electric current
Georg Ohm discovered that an electric current between two points is directly proportional to the voltage or potential difference between them, this became known as Ohm's law -
Faraday Electromagnetic Motors
Faraday went to work. inventing electromagnetic motors his MO worked due to electromagnetic rotation and the motion performed by circular magnetic force around an electrified wire in 1831 had his breakthrough. -
Modern Electric Motors and Generators.
Faraday's experiments led to the invention of modern electric motors, generators, he discovered how making electricity does work on magnetism and vice versa, and his young friend, the Scottish physicist James Clerk Maxwell, played the role of his Volta's mismatch and discovered the mathematics involved in induction in 1855 -

Maxwell's Complete Theory
Long article on the physical lines of force presented his complete theory of electromagnetism in parts about 1861 and 62 here he theorized that electromagnetic waves travel at the speed of light and that light must exist in the same medium as electrical energy and magnetic by connecting light electricity and magnetism Maxwell laid the groundwork for modern physics and his work was a major influence on Einstein -
Thomas Alva Edison invents the fuse
Electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit -
Indian physicist Jagadish Chandra Bose introduced the use of the semiconductor junction to detect radio waves
The junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor. -
German inventor Karl Ferdinand Braun invented cathode ray oscilloscope
An oscilloscope informally a scope is a type of electronic test instrument that graphically displays varying electrical voltages as a two-dimensional plot of one or more signals as a function of time. -
Edith Clarke invents the "Clarke calculator", a graphical calculator for solving line equations involving hyperbolic function, allowing electrical engineers to simplify calculations for inductance and capacity in power transmission lines
The “Clarke Calculator” greatly simplified calculations used to understand long transmission lines in the days before computers, allowing analysts to solve key equations ten times faster than previous methods.
