Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric currentthe part to be coated acts as the cathode negative electrode of an electrolytic cell. The electrolyte is a solution of a salt of the metal to be coated. Measurement data is performed to determine the voltage at no load and with the 12 v 3w led and lumination load.
