Volta Prize Volta Prize The Volta Prize (French: prix Volta) was originally established by Napoleon III during the Second French Empire in 1852 to honor Alessandro Volta, an Italian physicist noted for developing the electric battery. This international prize awarded 50,000 French francs to extraordinary scientific discoveries related to electricity. The prize was instituted by the Ministry of Public Instruction with the personal funding of the French Emperor, the selection committee was usually constituted by members of the French Academy of Sciences. Notable recipients have included, Heinrich Ruhmkorff, who commercialised the induction coil, and Zénobe Gramme, inventor of the Gramme dynamo and
Volta potential by its work function, and so dissimilar metals can show an electric potential difference even at equilibrium. The Volta potential is "not" an intrinsic property of the two bulk metals under consideration, but rather is determined by work function differences between the metals' surfaces. Just like the work function, the Volta potential depends sensitively on surface state, contamination, and so on. The potential is given by the formula: formula_1, where V is the potential, The Volta potential can be significant (of order 1 volt) but it cannot be measured directly by an ordinary voltmeter. A voltmeter does not measure vacuum
