The DC voltage V from the battery produces a DC current in the primary coil, but produces no voltage of any kind in the secondary coil. Transformers work because of Faraday's Law: the changing flux produced by the AC curr ...

... 1) Determine the resistance of your resistor using two dc multimeters and a voltage source. Vary applied voltage over a reasonable range and measure current through the resistor as a function of the voltage across the resistor. Find resistance by fitting a straight line (Ohm's Law) to the I-V line. ...

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.
