Which effect of current is primarily used in electroplating?

• A. Heat Effect
• B. Chemical Effect
• C. Physiological Effect
• D. Magnetic Effect

Answer: (B)

The main idea is that electroplating relies on the chemical effect of current. When a power source drives current through the electrolyte, metal ions in solution gain electrons at the cathode and deposit as metal onto the object being plated, while metal from the anode dissolves to replenish those ions. This is an electrochemical process—the current is used to cause chemical reactions, not just to heat the solution or to produce magnetic or physiological effects. So the deposition relies on the chemical change induced by the electric current, making the chemical effect the primary mechanism.
