Plating takes place when an electrical force (voltage) causes the positive-charged metal ions inn a plating bath to move towards the negative-charged cathode part of the plating circuit and combine with available electrons. At the cathode they are deposited as metal atoms. The movement of ions form one place to another (and electrons in the opposite direction) constitutes electrical current. The standard unit of measure for current is the Ampere. When we plate, we plate by amperage. An analogy can be drawn between amperage and voltage in a plating circuit.
