Preferred Label : electric potential difference;
Detailed label : electric potential difference of a galvanic cell, ΔV;
IUPAC acronym : emf;
IUPAC definition : Difference in the potentials of electrodes on the right and left of a galvanic cell.
When ΔV is positive, positive charge flows from left to right through the cell.;
Scope note : the limiting value of ecell for zero current flowing through the cell, all local charge
transfer and chemical equilibria being established, was formerly called emf (electromotive
force). the name electromotive force and the symbol emf are no longer recommended,
since a potential difference is not a force.;
