On the use of the Cole–Cole equations in spectral induced

In terms of equivalent circuits these formulations are based on serial and parallel connections of polarized and non-polarized elements These models converge at low chargeability values The Cole–Cole fitting procedure produces three equal model parameters (DC conductivity chargeability and exponent) regardless of the used formulation
