Difference in the potentials of electrodes on the right and left of a galvanic cell. When \(\Delta V\) is positive, positive charge flows from left to right through the cell.
The limiting value of \(E_{\text{cell}}\) for zero current flowing through the cell, all local charge transfer and chemical equilibria being established, was formerly called emf (@E01974@). The name @E01974@ and the symbol emf are no longer recommended, since a potential difference is not a force.
