  • A Anode and a direct current is used
  • B Cathode and an alternating current is used
  • C Anode and an alternating current is used
  • D Cathode and a direct current is used
Correct Answer: Option D
Explanation:
Plating requires ions to flow through an electrolyte in an electric field. Positive ions flow with the electric field, negative ions against the electric field. This electric field comes from a DC supply connected to the electrodes. While silver plating, Ag is the anode while the metal to be coated is the cathode.
