I. Introduction The world is blessed by the abundance of energy. It comprises various types of energy. One of this is electrical energy or electricity. Electricity is one of the most powerful forces in our lives. This term makes us to remind of that anything that an individual plug into the outlet, an electric current will flow to the device. It is the key component for the modern society everyone has today. Without this, our world is totally different. People continue to prosper the knowledge of producing electricity. As the result, inventions of electricity-producing products are made. Since its invention, the battery has become the most common power source for many household and industrial applications. A battery converts chemical energy to electrical energy. Each cell contains positive terminal, cathode and negative terminal, anode. There are many ways to construct a battery, as well as ways to control its generated output. Each component is highly needed to produce the expected outcome of the endeavor. It shows that searching new ways of producing electricity is not possible. It’s also impressive to know how vinegar can produce electricity and how it will help the environment. With this research, each individual’s curiosity will be captivated. II. Statement of the Problem 1. What is more convenient, commercial battery 2. qor vinegar battery? Explain why. 3. What is more reliable? Commercial battery or vinegar battery? Explain why. 4. Do you think vinegar battery can avoid our environment from destroying or harming it? Explain why. III. Formulation of the Hypothesis * Vinegar battery, because its materials like copper wire can be found in our home. In copper wire, we can use the copper wire on our old TV so that we don’t need to buy commercial batteries. * Vinegar
