In 1800 Alessandro Volta described the voltaic pile, the first electrical battery capable of continuously providing current, in a letter to the Royal Society in London. The letter, dated 20 March 1800, reported experiments conducted in 1799 and challenged the idea that electricity arose only from living beings.
Episodes
- Construction of the voltaic pile
Volta stacked alternating copper or silver and zinc discs separated by brine-soaked cloth or cardboard to increase electromotive force.
- Volta describes the voltaic pile to the Royal Society
Volta wrote to the London Royal Society on 20 March 1800 describing how his device produced electric current.
Background and detail
Background. The pile emerged from a professional disagreement between Volta and Luigi Galvani, whose experiments on frogs' legs had prompted a debate over galvanic response. Volta, an Italian chemist and physicist credited with inventing the electric battery, built the device in 1799 and then reported his results to the president of the Royal Society in London.
The Letter to the Royal Society. On 20 March 1800 Volta wrote to the London Royal Society describing the technique for producing electric current with his device. The communication took the form of a two-part letter to the society's president and was published in 1800, spreading knowledge of the invention among European scientists.
Construction and Significance. Volta stacked alternating pairs of copper (or silver) and zinc discs separated by cloth or cardboard soaked in brine, increasing the total electromotive force. The pile was the first electrical battery that could continuously provide current to a circuit, proving electricity could be generated chemically rather than solely by living beings.
