Capacitive Weak Links and Finite Load Lines

Abstract
A transformation is described which connects the already solved problem of a capacitive superconducting weak link driven by a constant‐current source to the physically more realistic situation of a source with finite load line. Hysteresis is found to persist although the loop may be quite narrow. It is shown that the minimum‐current dependence on the Josephson tunneling amplitude can distinguish between capacitive and inductive devices.
