Current sources, namely, current generators

Quantum hall systems consisting primarily of superconducting magnets, printed circuit boards (PCB) for generating quantum effects, room temperature resistance bridges, and hardware or magnet cooling dewars; current range extenders, namely, DC current sources in the nature of capacitors from 150 mA to 10,000 A and current comparator designed for higher currents and current sources, namely, DC current sources in the nature of capacitors from 150 mA to 10,000 A; current transformers; voltage dividers; null detectors, namely, devices for measuring, DC voltage sources ranging from micro-volts to thousands of volts; power analyzers; teraohmmeters; scanners; salinometers
