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.
-
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.
-
He developed the lightning rod -
Alessandro Volta created the first practical method of generating electricity, the first battery known as a voltaic cell
-
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 -
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 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.
-
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 -
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

Electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit
-
The junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor.
-
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. -
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.
