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

In contrast to the accumulator which can re-charge after use. Accumulator consists of a positive electrode, a negative electrode, and a liquid electrolyte. The electrolyte is made of materials dilute sulfuric acid. Positive electrode coated with lead diokasida (lead dioxide) and a negative electrode made of pure lead (sponge lead). A chemical reaction between two electrodes with liquid electrolyte lead to the displacement of electrons and produces a voltage between electrodes. Accumulator can re-charge by inverting the direction of current flowing accumulator.
