Inventions in the electrical equipment field started even before the invention of the incandescent lamp, by Thomas Edison, in 1879.
Earliest Electrical Inventions
Inventions started around the year 1740 when Stephen Gray invented “the electric conduction” which will lead the way to “glass friction generators”.
In 1800, Alessandro Volta invented “the battery”.
The first successful “arc lamp” was invented in 1808 by Humphrey Davy. However, the arc lamps only came in use in 1877 when it was used as streetlamps. Several countries illuminated their streets for the first time with arc lamps. These lights were too blazing to use inside houses.
Joseph Henry and Michael Faraday invented a basic “electric motor” in the year 1820. They discovered a relation between a magnet and a wire. Their findings were considered the basis of “a generator”.
In 1832, “the rudimentary dynamo” was invented by Hippolyte Pixii. Antonio Pacinotti worked on this invention and discovered “the continuous direct current” in 1860.
The year 1867 saw the invention of the “self-stimulating dynamo-electric generator” invented by Werner von Siemens, Charles Wheatstone, and Varley.
And then Thomas Edison discovered the “incandescent lamps” which were less bright for use inside homes. Thomas Edison inaugurated the first electrical central generating plant in Manhattan.
Without these early inventions, electrical manufacturing wouldn’t have become as evolved and indispensable as it is now.
