Not exact matches

Superconductors are materials that, when chilled, allow electrical current to flow freely, with zero resistance.
A compound of hydrogen and sulfur, when crushed at more than a million times Earth's standard atmospheric pressure, appears to whisk electrical current along without resistance at temperatures up to 203 kelvins.
When a user bends their fingers or thumb, the sensors stretch, and their electrical resistance goes up.
When Joachim and Gimzewski moved the STM tip down, slightly flattening their buckyball, the molecule's electrical resistance dropped 100-fold, allowing the current to flow more easily from the STM tip to the metal surface.
Some materials, when cooled to temperatures near absolute zero, reach zero electrical resistance.
