The current observed at a working electrode in an electrochemical experiment is often the sum of the current due to redox reactions occurring at the electrode surface and other currents such as capacitive charging/discharging of the electrode double layer.
The portion of the current usually of interest to an electrochemist is the current caused by the redox reaction(s) at the electrode surface. This portion of the current is called the Faradaic current.
