The Cottrell Experiment and Diffusion Limitation 3/3 - Electrochemical Double Layer - PalmSens
By A Mystery Man Writer
Description
In this chapter the electrochemical double layer and its features are discussed. The electrochemical double layer acts as a capacitor and every change in the potential of the electrode will induce a capacitive charging current that is caused by physics not by a chemical reaction. This current decays exponentially.
