Difference between ΔΦ and cell potential / EMF?

Postby nicolely2F » Thu Feb 27, 2020 2:58 pm

I'm not sure what the difference between the Galvanic potential ΔΦ and cell potential E(cell) aka EMF is. I know they both measure differences in potential between electrodes and have similar equations:
ΔΦ = Φcathode - Φanode
E(cell) = E(anode) - E(cathode)
If someone could explain the difference and usage, I'd appreciate it!

As I discussed in class the cell potential E(cell) aka EMF, is the maximum voltage difference in the limit of zero current.
Hope that helps.
