    How Electroplating WorksThe Anode and CathodePurpose of ElectroplatingElectroplating ExampleElectroplating is the application of electrolytic cells in which a thin layer of metal is deposited onto an electrically conductive surface. A cell consists of two electrodes (conductors), usually made of metal, which are held apart from one another. The electrodes are immersed in an electrolyte (a solution).When an electric current is turned on, positive ions in the electrolyte move to the negatively charged electrode, callSee more on thoughtco
