When electrons are forced down a conductive path, such as a wire, the movement produces electricity, or electric energy. - Definition & Examples, Heat Energy Lesson for Kids: Definition & Examples, What Is Electricity? The greater the voltage, the greater the potential to do work or move a charge. This is important to remember when working with electrical energy because the most common current carrier is an electron, which moves in the opposite direction compared with a proton. 8. For example, hydrogen ions, electrons, or metal ions may be more concentrated on one side of a membrane than the other, setting up an electrical potential that can be used to transmit nerve impulses, move muscles, and transport materials. We can use the analogy of a ball being thrown at a window. Common applications include space heating, cooking, water heating and industrial processes. The electricity can then do work such as light a bulb. Light bulbs convert electrical energy into light energy so we can see what we're doing in the dark. A battery is another source of electrical energy, except the electrical charges may be ions in a solution rather than electrons in a metal. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Well, what are these electric fields?
