Potential Difference of A Cell Assembled of Two Electrodes
See also: Galvanic cell#Cell voltage, Electrochemical cell#Cell potential, and Electrolytic cell#Anode and cathode definitions depend on charge and dischargePotential of a cell assembled of two electrodes can be determined from the two individual electrode potentials using:
ΔVcell = Ered,cathode - Ered,anode
or, equivalently,
ΔVcell = Ered,cathode + Eoxy,anode
This follows from the IUPAC definition of the electric potential difference of a galvanic cell, 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 ΔVcell is positive, then positive electrical charge flows through the cell from the left electrode (anode) to the right electrode (cathode).

Famous quotes containing the words potential, difference, cell and/or assembled:
“Children are potentially free and their life directly embodies nothing save potential freedom. Consequently they are not things and cannot be the property either of their parents or others.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“The difference is wide that the sheets will not decide.”
—English proverb, collected in John Ray, English Proverbs (1670)
“each in the cell of himself is almost convinced of his freedom,”
—W.H. (Wystan Hugh)
“According to the historian, they escaped as by a miracle all roving bands of Indians, and reached their homes in safety, with their trophies, for which the General Court paid them fifty pounds. The family of Hannah Dustan all assembled alive once more, except the infant whose brains were dashed out against the apple tree, and there have been many who in later time have lived to say that they have eaten of the fruit of that apple tree.”
—Henry David Thoreau (1817–1862)
