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 bus by induction or catenary. The first battery buses were mostly small, mini- or midi- buses. The improvement of battery technology from around 2010 led to the emergence of the battery bus, including heavier units such as twelve-meter standard buses and articulated wagons. Battery electric bus A battery electric bus is an electric bus that is driven by an electric motor and obtains energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source. Battery buses are equipped for charging with fixed pantographs at bus stops and in the Depot. Supercapacitors can be charged rapidly, reducing the
