Persistent currents and conductance of a metal loop connected to electron reservoirs

We have calculated the persistent current and the conductance of a normal metal loop connected to two electron reservoirs in the presence of magnetic flux. The geometry considered here facilitates simultaneous measurement of the persistent current and the conductance. We show that, in general, the magnitude of the persistent current in a loop depends on the direction of the direct current flow from one reservoir to another, a feature that can be experimentally verified.
