If a metal, such as Cu, is used as a working electrode, and another piece of the same metal is used as a reference electrode, then any potential applied is evenly divided between the working and reference electrode.

Question

Quizplus · Accepted Answer

Any potential applied to the working electrode will cause a redox reaction to occur at the surface of the electrode, which will generate a potential difference between the working electrode and the reference electrode. Therefore, the potential applied will not be evenly divided between the working and reference electrode.
