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.
An electric circuit is an interconnection of electric components such that electric charge is made to flow along a closed path (a circuit), usually to perform some useful task. [ 56 ] The components in an electric circuit can take many forms, which can include elements such as resistors , capacitors , switches , transformers and electronics .
The phonograph becomes faster and more convenient due to an electric motor. The electric motor brings on the first juke box with cylinders – even before flat disk records were widely available. Thomas Edison discovers thermionic emission. This effect forms the basis for the vacuum tube and the cathode ray tube.
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.
Maxwell had studied and commented on the field of electricity and magnetism as early as 1855/6 when On Faraday's lines of force [124] was read to the Cambridge Philosophical Society. The paper presented a simplified model of Faraday's work, and how the two phenomena were related.
In the early 1920s, there was a growing interest in the development of domestic applications for electricity. [39] Public interest led to exhibitions such featuring "homes of the future" and in the UK, the Electrical Association for Women was established with Caroline Haslett as its director in 1924 to encourage women to become involved in ...
