Simple cell

                                                  
                 A simple cell,as its name suggests is very simple in its structure,It consists of a beaker filled with dilute sulfuric acid.Two metal plates of zinc and copper ore dipped in the acid. The copper plate acts as a positive terminal and the zinc plate acts as a negative terminal.If these two terminal are connected by a conducting wire ti an electric bulb,electric current passes from the copper plate to zinc plate through the bulb.The electric circuit is completed.Thus,the bulb glows.A simple cell produces very small amour of electric current.Since it contains liquid.it is not portable.
