Comparative studies of dc and ac measurement methods used in dielectric spectroscopy

In this paper dispersive curves were measured by dc and ac methods. An attempt has been undertaken to verify the hypothesis that a dielectric containing space charge, examined by actual value method, gives different measurement results from the ones, examined by time response method. If the measurement results obtained by the both methods for the same sample do not differ from each other, it means that in the examined object no space charge exists.
