... side, a voltage drop so the voltage change is -V2. Then we go through R1 from the low V side to the high V side (since we are moving against the current flow I1): a voltage rise so the change is +I1R1. Finally, we go through R2, in the same direction as the current I2, so we have a voltage drop and ...

... hence derive an expression for V2 in terms of V1 and the values of the circuit components. The current, I, through a certain device varies with applied potential difference, V according to the relation I= IoekV where Io and k are constants. If R2 is replaced by this device, write down an expression ...

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.
