Electrical engineering

electricical engineering (history)
A short visual history of the invention of electronic devices in the field of electrical engineering. [2]
In engineering, electrical engineering is art of construction, design, and building of devices and machines tending to involve the flow of electric current through conductors, as in motors and generators, based on mathematical and scientific principles. [1]

In 1600, English chemist-physicist and physician William Gilbert—sometimes called the “father of magnetic philosophy”—published his De Magnete, the earliest known work treating both magnetism and electricity, was the first to use the New Latin term electricus to mean “like amber in it is attractive properties”, from the Greek word for amber, ήλεκτρον (ēlektron). Based on Gilbert’s usage, in 1646 term ‘electricity’ was introduced by Thomas Browne.

In 1630, German inventor Otto Guericke built a static machine generator.

In 1774, Swiss mathematical physicist Georges Le Sage invented the first electric telegraph consisting of 24 wires, each suitably spaced and insulated by means of glass partitions at frequent intervals, placed in a trough in the ground, according to which each wire represented a certain letter of the alphabet.

In 1776, Luigi Galvani made severed frog legs twitch via electric flow created via a dissimilar metal junction arch, after which he argued for an “animal electricity” theory to explain this phenomenon.

In 1800, Italian physicist Alessandro Volta, in aims to disprove Galvani’s animal electricity theory, invented the battery otherwise known as the voltaic pile.
