Redox potential (reduction potential of ORP) is an abbreviation for reduction and oxidation potential. A redox potential is the potential value when the reduction and oxidation of a certain metal or other chemical are in balance with each other. Redox potential is measured in Volt (V).
A potential is nothing other than the voltage or electrical voltage of a specific (liquid) substance.
The compliance voltage is the maximum voltage that can be applied between the working and counter electrode. Another name could be the maximum cell potential.
In this chapter the two main ways of visualizing Electrochemical Impedance Spectra (EIS), the Nyquist and Bode plot, are presented and it is explained how different EIS of easy electronic circuits will be plotted in the Bode and Nyquist plot. This demonstrates the advantages and disadvantages of the two plots as well as serving as a foundation to understand the analysis of EIS by utilizing equivalent circuits.
If the potential of the electrode is changed, for example during a potential step, the amount of charge the capacitor stores changes, and a current will flow that has no chemical but only a physical meaning. This is the current that charges or discharges the capacitor also known as capacitive charging current or short capacitive current.
