Abstract: We study the transport properties of a metallic ring threaded by a magnetic flux varying linearly in time $\Phi_M(t)=\Phi t$ with a constriction and connected to two external particle reservoirs. This setup contains as limiting cases the experimental arrangements used to define Kubo and Landauer conductances. We employ a formalism based in Baym-Kadanoff-Keldysh non-equilibrium Green functions to calculate the conductance of the system and the dissipated power. We compare the transport behavior in different limits of the geometrical configuration. Copyright Springer-Verlag Berlin/Heidelberg 2003
