Current electricity is produced by electrons on the move in a continuous, unbroken path or "circuit". It can only exist in a conductor, which is a material such as a metal that allows electrons to pass through it. To make these electrons move, a source of energy or a driving force is needed. Chemical energy is the source of power in a battery-powered circuit.
Background Terms:
Electroplating is more than a century old. You can see many examples of electroplating around you. The "tin can", for example, is actually a steel can that has been plated with a protective layer of tin. Nowadays many "tin cans" are actually plated with chromium instead of tin, because it is more resistant to corrosion. New applications for electroplating are being experimented with right now. To replace worn or damaged human joints by synthetic ones, doctors need strong, light, and resistant materials. One material that has shown promise in experiments is made by plating a light-weight alloy with a thin coat of tantalum.
