Volta was born in Como, Italy. 1772, he began to study the manufacture of electric motors. Three years later, he invented the starting disk. From 65438 to 0779, he was a professor of physics in university of pavia, and presided over physics lectures for more than 20 years. Volta realized that the contact between two metals is a necessary condition to generate current. As long as two metals are connected with another conductor of the second kind (some chemical solutions or biological organs) to form a loop, current can be generated. After that, Volta spent three years matching various metals and did many experiments to classify various conductors. Volta is a kind of thing called "Volta Stack", which uses a large number of copper discs and iron or galvanized discs alternately, and then separates them with multiple layers of cloth soaked in salt solution.
1800 On March 20th, Volta sent a manuscript describing his invention to the Royal Society of London. Later, people called this device electric pile. Volta reactor is better than Leiden bottle, which can connect the metal wires at both ends of the reactor to obtain continuous current. This is the embryonic form of modern batteries, and we use it in photography and many other devices today. With the invention of voltaic reactor, it is possible for people to obtain relatively stable current for the first time, which provides conditions for further research and enters the modern stage of scientific quantitative research.
Today, the voltaic pile and the unit of potential "Volt" are named after this talented physicist.
