We liked [Tom’s] advice from his old instructor: you aren’t really ever measuring a resistance. You are measuring a voltage and a current. With a four-wire measurement, one pair of wires ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required.

This feature helps eliminate the need to dial in the correct range of an electronic measurement when taking a reading.

Multiterminal Josephson junctions, nanoscale devices with unique electronic properties, comprise non-superconducting metallic ...
