This was a single-plate capacitor used to produce imbalances of electric charge through the process of electrostatic induction. He also devised experiments such as the ignition of gases by an electric spark in a closed vessel – much like a spark plug in an internal combustion engine. Further work led up to the development of the voltaic pile, a forerunner of the electric battery. He also determined that the most effective pair of dissimilar metals to produce electricity was zinc and silver. The term “volt” is derived from his name because of work. A volt is a measurement unit of electrical potential or electromotive force. Read more…
