  text: Attributing features of electrochemical impedance spectra to electrochemical
    phenomena is both crucial and frequently ambiguous. To elucidate the origin of
    the ohmic part of the spectrum, activated carbon electrodes were prepared with
    different contents of polyacrylic acid as binder. Their impedance spectra and
    cyclic voltammograms were recorded using sulfuric acid of five different concentrations
    as the electrolyte. To distinguish electrolyte resistance and resistances related
    to the activated carbon layer of the electrode, the specific electrolyte conductivity
    was independently measured and compared against the ohmic part of the electrochemical
    impedance spectra (EIS). The capacitive cyclic voltammograms show larger resistive
    contributions with higher scan rate and lower electrolyte conductivity. Comparing
    the ohmic part of the EIS to the specific resistance of the electrolyte, a linear
    function with no statistically significant offset was found. The ohmic part of
    the EIS, thus, reflects the electrolyte resistance, not that of the carbon electrode.
