Henry Cavendish Electricity

Thales of Miletus was the first who observed the electrical phenomena when, to rub a bar of amber with a cloth, he noticed that the bar could attract light objects. While the electricity was still considered little more than a lounge show, the first scientific approaches to the phenomenon were made in the 17TH and 18th centuries by systematic researchers such as Gilbert, Von Guericke, Henry Cavendish, and Watson. These observations begin to bear fruit, with Galvani, Volta, Coulomb and Franklin, and, already at the beginning of the 19th century, Ampere, Faraday and Ohm. However, the development of a theory that unify the electricity with magnetism as two manifestations of the same phenomenon was not reached until the formulation of Maxwell’s equations (1861-1865).

Its first widespread practical application was electric telegraph of Samuel Morse (1833), which revolutionized telecommunications.

The growing succession of applications that this availability was made of electricity one of the main driving forces of the second industrial revolution. Artificial lighting modified duration and hourly distribution of individual and social activities, industrial processes, transportation and telecommunications. The development of quantum mechanics in the first half of the twentieth century laid the Foundation for the understanding of the behavior of electrons in different materials. This knowledge, combined with technologies developed for radio broadcasts, allowed the development of the electronics, which reached its peak with the invention of the transistor. Development, miniaturization, increased speed and the lowering cost of computers during the second half of the 20th century was possible thanks to the good knowledge of the electrical properties of semiconductor materials. This was essential for the formation of the society of the information of the third industrial revolution comparable in importance with the generalization of the use of automobiles.

Storage problems of electricity, their transport over long distances, unfortunately, have not yet been resolved efficiently. Likewise, the proliferation of all kinds of practical applications of electricity has been one of the main factors of the modern development of electrical assemblies or new forms of electricity conservation. In final we will consider, for example, an electrical installation. An electrical duct mount that uses air as the medium insulative is capable of transmitting electrical energy in the EHV and UHV levels. The duct mount comprises a duct cover which has a concentric cylindrical conductor arranged in this with a protector cylindrical metal interposed between the conductor and the chute cover. The entire space within the duct cover is filled with air under normal atmospheric conditions.
