The difference between the electrode potentials of two electrodes when no current is drawn through the cell is called ___________.

Cell potential is defined as the potential difference between the two electrodes of a galvanic cell and it is measured in volts. It is the difference between the electrode potentials (reduction potentials) between the cathode and anode. The cell potential is known as electromotive force or emf when no current is drawn through the cell. The correct answer is (ii).
