Electromotive Force

[Kyle Walsh 2J]

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!

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

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.

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

So, EMF/ E-naught is standard conditions where as E is non standard?

So, EMF/ E-naught is standard conditions where as E is non standard?

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.
