  1. A continuous displacement of free electrons, or electricity, in the wire was then observed. The work of Faraday and Henry inspired other scientists and accelerated discoveries. In 1882, Croatian engineer Nikola Tesla perfected the alternator, a device capable, as its names indicates, of producing an electrical current that alternates constantly back and forth on a messenger wire. The same year, French chemist Lucien Gaulard presented a transformer capable of changing the voltage of alternating current. These two inventions greatly facilitated the large-scale production and transportation of electrical energy over long distances
