The batteries.


The first battery was made by Alessandro Volta in 1799. This was a series of pairs of discs of zinc and copper, separated from each other by pieces of cardboard or felt impregnated water.
The battery more used is a battery Lenclanché. This battery was formed by a solution of ammonium chloride in which electrodes are immersed zinc and coal, cover for a paste of manganese dioxide and carbon dust.
The Batteries are a primary generator. This energy is accessible through two terminals that have the battery, called poles, electrodes, or terminals. One is the positive pole or the other is anode and the negative terminal or cathode. The fundamental structure of a battery consists of pieces of two different metals brought into a liquid conductor of electricity.
