The problems of determination of the effective area of the measurement electrode during the evaluation of volume resistivity and electrical permittivity based on measurements in three electrode system are discussed. The presented analysis shows that because of the inaccuracies of formulas given in the standards concerning the effective area of the measurement electrode, the calculation of the volume resistivity and electrical permittivity might be encumbered with errors. The values of these errors are presented graphically. It has been shown that the factor of the measurement electrode extension at the electrical permittivity measurements also depends on electrical permittivity.
