Electromotive Force
Hi, I was just curious as to what specific qualities electromotive force has when compared to cell potential, as I have it written down in my notes but not much context as to the definition. Thanks!

Re: Electromotive Force
Hi! My understanding is that electromotive force and cell potential are the same! Hope this helps!

Re: Electromotive Force
I think they're generally the same. A quick online search said that EMF is the voltage induced from a source, but it's measured in volts as is cell potential.

Re: Electromotive Force
The cell potential is the difference in potentials of the cathode and anode. When electrons are transferred, this creates an electromotive force, or EMF.

E is the cell potential at non-standard conditions and E-naught is the cell potential under standard conditions, but as for as I know EMF / E-naught does not really equate to anything. However, it is worth mentioning that when referring to E or cell potential for this class, we are referring to the EMF, which is the cell potential at its maximum value. This is because once the current starts flowing/increasing, the voltage inevitably starts decreasing.
