Electrical engineering credited with establishing the term "electricity". He also designed the versorium: a device that detects the presence of statically charged objects. In 1762 Swedish professor Johan Carl Wilcke invented a device later named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday (the discoverer of electromagnetic
Marsilio Landriani to convince Landriani to change over to the new chemistry, but he never was able to decide between phlogiston and oxygen. After 1790 he dealt exclusively with chemical applications of electric phenomena, and the improvement of physics and meteorology instruments. During his career he enjoyed a popularity comparable only to that of Alessandro Volta and Lazzaro Spallanzani, of all Italian scientists of that time. Marsilio Landriani Marsilio Landriani (Milan, 1751 – Vienna, 1815) was an Italian chemist, physicist and meteorologist. He became known with his first book, (Physical investigations on the salubrity of air), published in 1775. In it he
