Elemen Volta

Element Volta

Element Volta electric element is the simplest. Volta name taken from the name of the creators of the first, namely Alessandro Volta in 1799. This element is made from a zinc plate and a copper plate dipped in sulfuric acid (H2SO4). The end of the second plate are poles that have a potential difference of about IV copper potential is higher than the potential zinc. Therefore, copper is a pole (+) and zinc are the polar (-). If both poles are connected, the chemical reaction occurs in the plate. As a result, zinc plate becomes negatively charged and positively charged copper plate. The electrons flow from zinc to plate copper plate. A small lamp will light up if connected to the second plate. Element Volta has a weakness, which can only work within a relatively short time. Lights can be lit only briefly, then lights will be extinguished. This is because when an electric current to flow, bubbles arise in the solution. These bubbles stick to the copper and prevents electrons moving toward the copper plate. As a result, electric current gradually decreases and the lamp goes out. Events gas bubbles attach to the copper-called polarization. Lights can be lit again if the bubbles were removed from the copper plate. As a result of the incident polarization, the voltaic elements are not suitable for use in electrical equipment in everyday life.
