So the units of electrical work divided by charge is Joules divided by Coulomb. And this equals our changing electrical potential, which is also the voltage difference. And which is also what we said before is the electromotive force or EMF. Now, whenever we talk about the EMF of an electrochemical cell, we could also call our EMF the cell voltage because we're talking about an electrochemical cell. And the cell voltage shows how much work can be done for every coulomb produced by a redox reaction in an electrochemical cell. So that basically says that when in an electrochemical cell, one coolant of charge moves from the anode to the cathode, x amount of work can be done.
