Alessandro Volta
Numéro d’image : 12066644
| Italian physicist Count Alessandro Volta (1745- 1827) posing with his newly-invented battery or "Voltaic pile". Volta was the first to show that an electrical current flowed when two dissimilar metals were brought into contact. In 1800 he constructed a device which used this effect to produce a large flow of electricity. Bowls of salt solution were connected together by metal strips,each composed of copper at one end & tin or zinc at the other,and a current was produced. A compact version of this,using a stack of discs of copper,zinc & cardboard moistened with salt solution,is seen here | |
