... The behavior of the system in Fig. 3 is in fact exactly the same as the behavior of the system in Fig. 1. When the input (current source) steps up, the input current doesn’t match the inductor current, which is still zero, so initially the difference goes through the resistor, and a voltage (v = iR) ...

Josephson voltage standard
A Josephson voltage standard is a complex system that uses a superconductive integrated circuit chip operating at 4 K to generate stable voltages that depend only on an applied frequency and fundamental constants. It is an intrinsic standard in the sense that it does not depend on any physical artifact. It is the most accurate method to generate or measure voltage and, by international agreement, is the basis for voltage standards around the World.
