Abstract
Using the conventional Bohr interpretation of a <<quantum measurement> > as an interaction between a quantum object and a classical apparatus , we consider the voltage-current characteristics of a singly connecte d weak link. We employ a well-known electrical engineering model using a shunt resistor. The equations are described in a simple Lagrangian form eliminating the need to consider explicitly the dynamics of the d issipative degrees of freedom internal to the resistor.
