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
Abraham Bennet Abraham Bennet Abraham Bennet FRS (baptised 20 December 1749 - buried 9 May 1799) was an English clergyman and physicist, the inventor of the gold-leaf electroscope and developer of an improved magnetometer. Though he was cited by Alessandro Volta as a key influence on his own work, Bennet's work was curtailed by the political turbulence of his time. Abraham was baptised in Taxal, Derbyshire, the son of another Abraham Bennet, a schoolmaster, and his wife Ann "née" Fallowes. There is no record of him having attended university but he is recorded as a teacher at Wirksworth Grammar School as "MA".
