Consider an electrochemical cell consisting of a zinc electrode in one half-cell and a copper electrode in the other half-cell. The zinc electrode has a surface area of 5 cm² and is placed in a 0.1 M ZnSO₄ solution, while the copper electrode has a surface area of 10 cm² and is placed in a 1.0 M CuSO₄ solution. Calculate the polarization of the cell when a current of 0.5 A is passed through it.
