Electromotive force

Postby briannam_1F » Sat Mar 14, 2020 12:46 pm

Can someone explain what an electromotive force is? Also, does anyone remember what day it was talked about in lecture, if it was discussed in lecture.

I think lecture 15 was when he first introduced e.m.f.

The electromotive force of the cell is the potential difference between the electrodes of a galvanic cell, in the scenario where there is very little, or no current flow. It is the maximum p.d between the cell electrodes and is symbolised as the E value of the cell.

Electromotive force is a difference in the potential of two reactions that give rise to an electric current. This concept was given in the first lecture of electrochemistry.
