1911: First film studios are created in Hollywood and Potsdam- Babelsberg . 1912: The first radio receiver is created, in accordance with the Audion principle. 1913: The legal battle over the invention of the electron tube between Robert von Lieben and Lee de Forest is decided.
The first half of the 700-page book is a history of the study of electricity. It is parted into ten periods, starting with early experiments "prior to those of Mr. Hawkesbee", finishing with variable experiments and discoveries made after Franklin's own experiments.
In 1600, the English scientist, William Gilbert extended the study of Cardano on electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. [7] He coined the Neo-Latin word electricus ("of amber" or "like amber", from ήλεκτρον [ elektron ], the Greek word for "amber") to refer to ...

Streetcars created enormous demand for early electricity. This Siemens Tram from 1884 required 500 V direct current, which was typical. Much of early electricity was direct current, which could not easily be increased or decreased in voltage either for long-distance transmission or for sharing a common line to be used with multiple types of electric devices.
1800 – William Nicholson, Anthony Carlisle and Johann Ritter use electricity to decompose water into hydrogen and oxygen, thereby discovering the process of electrolysis, which led to the discovery of many other elements. 1800 – Alessandro Volta invents the voltaic pile, or "battery", specifically to disprove Galvani's animal electricity ...
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge.Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
