Andrea Naccari
Encyclopedia
Andrea Naccari is notable for his study of the thermoelectric properties of metals, the photoelectric effect
of metals immersed in liquids, and the electrical conductivity of gases and liquid dielectric
s. He showed that the variation in the electrical resistance
of distilled water was due largely to the solubility of the glass of the receptacle in which it was contained.
He obtained his PhD in pure maths in 1862 at the University of Padua

Photoelectric effect
In the photoelectric effect, electrons are emitted from matter as a consequence of their absorption of energy from electromagnetic radiation of very short wavelength, such as visible or ultraviolet light. Electrons emitted in this manner may be referred to as photoelectrons...

Liquid dielectric
A liquid dielectric is a dielectric material in liquid state. Its main purpose is to prevent or rapidly quench electric discharges. Dielectric liquids are used as electrical insulators in high voltage applications, e.g. transformers, capacitors, high voltage cables, and switchgear...

Electrical resistance
The electrical resistance of an electrical element is the opposition to the passage of an electric current through that element; the inverse quantity is electrical conductance, the ease at which an electric current passes. Electrical resistance shares some conceptual parallels with the mechanical...

University of Padua
The University of Padua is a premier Italian university located in the city of Padua, Italy. The University of Padua was founded in 1222 as a school of law and was one of the most prominent universities in early modern Europe. It is among the earliest universities of the world and the second...

Francesco Rossetti
Francesco Rossetti was a notable Italian experimental physicist.Son of Giovanni Battista, he started his education in his natal town Trento. He then attended the University of Padova and, from 1854 to 1857, the University of Vienna, where he heard classes in mathematics, chemistry and physics, and...
