In this paper, I consider the Josephson junction with the graphene interlayer. This contact consists of two superconducting reservoirs, superconducting leads connecting them, and a graphene interlayer. The dependence of the electric current flowing through this structure is derived. The calculation takes into account the Andreev reflection, normal transmission and transmission with the conversion of an electron into a hole. The formula is derived, and a graph is plotted for the power required for the transition of a superconducting line to a normal state. The differential conductivity of the system is considered. Based on the results of the work, a theory describing the processes in the Josephson junctions with the graphene interlayer was obtained.
