WebAnd this voltage is the Standard Cell Potential. So E naught of the cell is equal to positive 1.10 volts. And the Standard Cell Potential depends on the potentials for the two half reactions that make up the cell. So if we know the potentials for the half reactions that make up the cell, we can calculate the standard potential of any galvanic cell. WebTo calculate the cell voltage, E ° cell = E ° cathode – E ° anode, using the values from the standard reduction potential table. For example, in the Zn/Cu cell, the Zn is connected to the black wire (anode) and the Cu is connected to the red wire (cathode). For copper, the E° = 0.34 V. For zinc, the E° = -0.76 V.
