CHEMISTRY GLOSSARY

electrostatics    →   elektrostatika

Electrostatics study of electric charges at rest.

Gauss’ law for electrostatics    →   Gaussov zakon za elektrostatiku

Gauss’ law describes the relation between charge and electric field in static situations, so it is equivalent to Coulomb’s law, which can be derived from Gauss’ law. Gauss’ law states that the net flux of electric field, Φ, through an imaginary closed surface, S, - a Gaussian surface - is equal to the net charge, q, inside that closed surface:

where electric flux Φ through Gaussian surface is given by:

ε₀ is the permittivity constant and dS is a surface element.

Volta, Alessandro    →   Volta, Alessandro

The Italian physicist Alessandro Giuseppe Antonio Anastasio Volta (1745-1827) was the inventor of the voltaic pile, the first electric battery (1800). In 1775 he invented the electrophorus, a device that, once electrically charged by having been rubbed, could transfer charge to other objects. Between 1776 and 1778, Volta discovered and isolated methane gas (CH₄). The electrical unit known as the volt was named in his honor.
