Potential of a cell assembled of two electrodes can be determined from the two individual electrode potentials using

:<math>\Delta V_\text{cell} =  E_\text{red,cathode} - E_\text{red,anode}</math> however , it depends.

or, equivalently,

:<math>\Delta V_\text{cell} =  E_\text{red,cathode} + E_\text{oxy,anode}.</math>

This follows from the IUPAC definition of the electric potential difference of a galvanic cell,<ref>{{GoldBookRef |title=electric potential difference, ΔV ''of a galvanic cell'' |file=E01934}}</ref> according to which the electric potential difference of a cell is the difference of the potentials of the electrodes on the right and the left of the galvanic cell.  When {{math|Δ''V''<sub>cell</sub>}} is positive, then positive electrical charge flows through the cell from the left electrode ([[anode]]) to the right electrode ([[cathode]]).
