Abstract

Many students learning electrochemistry do not understand how current flows from one electrode to the other in an electrochemical cell. This is generally because interfacial phenomena and ionic conductivity in the electrolytic solution tend to be treated separately by chemistry teachers. An easy way to improve students' understanding of "how it works" is to compute the two dimensional electric potential distribution in the cell and to make a gravitational analogy. Current flows from one electrode to the other just like a ball would do in a gravitational field.
