Resistive and inductive transitions are measured on the same Bi2Sr2CaCu2O8 ceramic. The transition curves present accidents which appear to be correlated and amenable to physical interpretation in quantitative agreement with a granular description. We consider two characteristic temperatures: Ts which marks the appearance of superconductivity and Tc < Ts below which long-range coherence occur. In the paracoherent region Tc < T < Ts the excess conductivity is in good agreement with a power law Δσ ∝ |1−T/Tc|−γ with γ = 2.7 while in the coherent region T < Tc the field of first flux penetration is satisfactorily described by a power law H1(T) ∝ (1−T/Tc)n with n = 2.7. The validity of this description is corroborated by the correct prediction, from resistivity data, of the distance d congruent with 0.3±0.1 nm between CuO2 layers in the unit cell.
