Electricity is one of the most important forces in our lives today, and without the ability to harness and utilize electricity, the world would be a very different place. However, many people do not really understand electricity, and it can be hard to agree on a concrete definition. Electricity is a natural phenomenon and it can take a variety of different forms. Electricity is the flow of an electric charge, but it helps to go a bit deeper to understand where that electric charge originates.
All atoms contain particles, protons and neutrons. Protons are positively charged and neutrons are neutral. Electrons surround the atom’s nucleus, and they have a negative charge. The negative and positive elements in an atom, the electrons and protons, are generally the same. When some type of external force disrupts this balanced nature, the atom may lose an electron. When the electron is free, it creates, or is a part of, an electric current.
