Contact tension (also known as the contact electromotive force) is a force suggested by Alessandro Volta in 1800 to explain how electricity is generated in an electric battery or, as it was then called, the Voltaic pile. The validity of this model versus one based upon chemical reactions was debated for much of the 19th century in what has been called the Galvani-Volta controversy.
