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
Plug-in electric vehicles in the United States will be plug-in hybrids or full battery electrics by 2030. The U.S. Energy Information Administration (EIA) in its 2017 Annual Energy Outlook 2017 projected that all-electric vehicles sales in the United States will increase from less than 1% in 2016 to 6% in 2040 of total light-duty vehicles sold in the country, and plug-in hybrid electric vehicle sales will increase from less than 1% to 4% over the same period. According to the EIA projected sales of light-duty battery electric, plug-in hybrid electric, and hydrogen fuel cell vehicles will reach 1.5 million in 2025, about 9% of projected total sales
