WebElectroplating Process Steps. In an electroplating process, the object to be electroplated is made the cathode (i.e. connected to the negative terminal of DC source) in the solution of a salt of the coating metal. The articles which are to be electroplated are suspended into the plating solution. The anode is also generally of the same metal. tegar aku yang dulu chordtelaWeb5 jan. 2024 · Find the total charge passed through the circuit.
