Tempio Voltiano Tempio Voltiano The (Italian; Volta Temple in English) is a museum in the city of Como, Italy that is dedicated to Alessandro Volta, a prolific scientist and the inventor of the electrical battery. Volta was born in Como in 1745, held his first professorship there until 1779, and retired to Como in 1819. The neoclassical building was designed by Federico Frigerio (1873–1959). It was completed in 1927 to celebrate the 100th anniversary of the scientist's death, but it was inaugurated only in 1928. It hosts a collection of scientific instruments used by the physicist including his early voltaic piles (batteries).
Volta potential electrostatic potentials, but instead the difference in Fermi level between the two materials, a difference that is exactly zero at equilibrium. The Volta potential however corresponds to a real electric field in the spaces between and around the two metal objects, a field generated by the accumulation of charges at their surfaces. The total charge formula_2 over each objects' surface depends on the capacitance formula_3 between the two objects, by the relation formula_4 where formula_5 is the Volta potential. It follows therefore that the value of the potential can be measured by varying the capacitance between the materials by a
