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
Battery electric multiple unit Merseyrail Wirral Line and extend into the underground section of Liverpool's city centre. The line is diesel train operated unable to progress into the electric 3rd rail underground Birkenhead and Liverpool Merseyrail tunnels. The diesel operated line terminates at Bidston railway station in Birkenhead, with passengers having to change trains at Bidston to proceed onto the Merseyrail electric network. Network Rail proposed using dual battery powered/3rd rail pickup rolling stock without full electrification of the 27 mile long line, providing a cheaper method of increasing connectivity into the electrified underground sections of the Birkenhead and Liverpool Merseyrail Wirral Line.
