Calculate the current density of an electrochemical cell where a nickel electrode is oxidized to form nickel (II) ions, while a copper electrode is reduced by the nickel (II) ions. The cell has a voltage of 0.65 volts and a resistance of 50 ohms. The surface area of the nickel electrode is 10 cm² while that of the copper electrode is 15 cm². The current density of the electrochemical cell is expressed in A/cm².
