- Widerstandsüberspannung
- de
- Definition Überspannung, die auftritt, wenn die Geschwindigkeit der Elektrodenreaktion ausschließlich durch den Widerstand der elektrochemischen Doppelschicht bestimmt ist Reference DECHEMA
- Comment Die Widerstandsüberspannung beruht oft auf der Entstehung einer Schicht hohen Widerstandes auf der Elektrodenoberfläche

- Definition "ir drop [ IATE:1369802 ] in the electrolyte solution of a three-electrode cell between the working and the reference electrodes" Reference "Corrosion Doctors. Electrochemistry Dictionary, http://corrosion-doctors.org/Dictionary/Dictionary-S.htm [14.10.2013]"
- Comment This ir drop (which is expressed as a potential) is always included in the measured potential of the working electrode. Therefore, it is important to minimize this error, and to place the reference electrode as close as possible to the working electrode (see Luggin tip). One can correct for the ir drop to obtain the real electrode potential, or in some cases one can compensate for the ir drop during potential control. During the measurement of an electromotive force (potential measurement without any current flowing), the ir drop is always zero, and the position of the reference electrode is immaterial.
