An additional 800 people die in fires caused by faulty electrical systems every year.
Thousands are shocked and burned as the result of accidental contact with electricity every year.
Electricity, or electric current, is the flow of electrons from one atom to another in any material. Materials that allow electricity to flow easily are called conductors. Most metals, such as copper and aluminum, make good conductors of electricity. Insulators are materials that do not allow electricity to flow through them. Good examples of insulators are glass, plastic, and rubber.
