Abstract :
The paper deals with the concept of effective resistivity to use in problems expressed in terms of phasor quantities under a sinusoidal time varying excitation. A single time-harmonic solution with several definitions of the effective electric conductivity is given. The losses in HTS tape and cable are obtained in steady state and the results are validated through Norris formulae.
