approximately 1893: The selenium phototube invention allows the conversion of brightness values into electrical signals. The principle is applied in wirephoto and television technology for a short time. Selenium is used in light meters for the next 50 years.
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.
The donation of his extensive electrical library was a considerable boon for the fledgling Society. Michael Faraday portrayed by Thomas Phillips c. 1841–1842 [25] Development of the scientific basis for electrical engineering, using research techniques, intensified during the 19th century.
Electric power transmission, the tools and means of moving electricity far from where it is generated, date back to the late 19th century. They include the movement of electricity in bulk (formally called "transmission") and the delivery of electricity to individual customers ("distribution"). In the beginning, the two terms were used ...
Today the vast majority of publications no longer refer to electricity as meaning electric charge. Instead they speak of electricity as electromagnetic energy. The definition has drifted even further, and many authors now use the word electricity to mean electric current , energy flow , electrical potential , or electric force. Others refer to ...
