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 vehicle vehicles, and a wide range of other devices. Certain manufacturers specialize in electric-powered "in plant" work machines. Three-wheeled vehicles include electric rickshaws, a powered variant of the cycle rickshaw. The large-scale adoption of electric two-wheelers can reduce traffic noise and road congestion but may necessitate adaptations of the existing urban infrastructure and safety regulations. From India, AVERA new and renewable energy company is going to launch two models of electric scooters at the end of 2018, with Lithium Iron Phosphate Battery technology. China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping
