    en
    Sainmhíniú the difference between the cell voltage (with a current flowing) and the open-circuit voltage (ocv) Tagairt "Corrosion Doctors. Electrochemistry Dictionary, http://corrosion-doctors.org/Dictionary/Dictionary-O.htm [14.10.2013]"
    Nóta "The overvoltage represents the extra energy needed (an energy loss that appears as heat) to force the cell reaction to proceed at a required rate. Consequently, the cell voltage of a galvanic cell (e.g., a rechargeable battery during discharging) is always less than its ocv, while the cell voltage of an electrolytic cell (e.g., a rechargeable battery during charging) is always more than its ocv. Occasionally also referred to as ""polarization"" of the cell. The overvoltage is the sum of the overpotentials of the two electrodes of the cell and the ohmic loss of the cell. In electrochemistry, overvoltage is not a synonym of overpotential [ IATE:1369777 ], although, unfortunately, the terms overvoltage and overpotential are sometimes used interchangeably."

    Sainmhíniú "ir drop [ IATE:1369802 ] in the electrolyte solution of a three-electrode cell between the working and the reference electrodes" Tagairt "Corrosion Doctors. Electrochemistry Dictionary, http://corrosion-doctors.org/Dictionary/Dictionary-S.htm [14.10.2013]"
    Nóta 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.
