Electric current can be generated through the movement of electrons due to a chemical process.<\/span> A battery or accumulator produces electron flow continuously through the chemical reaction between the two electrodes of different kinds.<\/span> Electrode is a solid conductor in which an electrical current can flow through it.<\/span> One electron collecting electrode and the other electrode gives electrons.<\/span> Dry batteries using two electrodes of different metal materials are inserted into the electrolyte paste material.<\/span><\/p>\n Electrical current is produced when a chemical reaction in the electrolyte paste between two electrodes, which causes electron flow.<\/span> Construction dry battery shown in Fig 1:24.<\/span> Dry battery container made of zinc plate, a negative electrode, whose function is to provide electrons.<\/span> Charcoal rod is placed in the center, which serves as the positive electrode collects electrons.<\/span><\/p>\n The space between the two electrodes is filled by electrolyte is typically made of mangandioksida shaped pasta.<\/span> Pasta manganese dioxide acid caused a chemical reaction between carbon and zinc electrodes.<\/span> The chemical reaction of zinc moving electrons, causing the electrons flow.<\/span> The top of the battery is sealed so that the electrolyte does not dry pasta.<\/span> Dry battery will lose its energy after use.<\/span> The energy that has been used can not be replaced again.<\/span><\/p>\n
