The c-axis resistivity of Bi₂{Sr}₂CaCu₂{O}ₓ$ single crystals shows a magnetic-field-dependent peak below the zero-field ${T}c$. We find good agreement with the temperature and field dependence of the peak, by modeling the c-axis conduction as a series stack of Josephson tunnel junctions. For intermediate values of the Josephson coupling, we predict such a peak and verify it by measurements on discreet, thin-film Josephson junctions. The exaggerated effects in Bi₂{Sr}₂CaCu₂{O}ₓ$ result from its unusually large energy gap and fluctuations.
