Aluminum electrolytic capacitor or peak voltages is not possible. In every case transients arise, the application has to be carefully approved. Electrolytic capacitors with solid electrolyte cannot withstand transients or peak voltages higher than the surge voltage. Transients for this type of electrolytic capacitor may destroy the component. Electrolytic capacitors are polarized capacitors and generally require an anode electrode voltage to be positive relative to the cathode voltage. However, the cathode foil of aluminum electrolytic capacitors is provided with a very thin, natural air-originated oxide layer. This oxide layer has a voltage proof of approximately 1 to 1.5 V. Therefore, aluminum electrolytic capacitors
Standard electrode potential is sufficient to calculate either one of the potentials. Therefore, standard electrode potential is commonly written as standard reduction potential. The electrode potential cannot be obtained empirically. The galvanic cell potential results from a "pair" of electrodes. Thus, only one empirical value is available in a pair of electrodes and it is not possible to determine the value for each electrode in the pair using the empirically obtained galvanic cell potential. A reference electrode, standard hydrogen electrode (SHE), for which the potential is "defined" or agreed upon by convention, needed to be established. In this case SHE is set to
