Meaning of CAPACITIVE CURRENT (DENSITY) in English
- CAPACITIVE CURRENT (DENSITY)
"The current (or current density) flowing through an electrochemical cell that is charging/discharging the electrical double layer capacitance. This current does not involve any chemical reactions (charge transfer), it only causes accumulation (or removal) of electrical charges on the electrode and in the electrolyte solution near the electrode. There is always some capacitive current flowing when the potential of an electrode is changing, and the capacitive current is generally zero when the potential is constant. Also called ""non-faradaic"" or ""double-layer"" current. Contrast with faradaic current. Capacitive current can also flow at constant potential if the capacitance of the electrode is changing for some reason, e.g., change of electrode area or temperature. "
