Devices could eliminate the strong magnetic fields currently required to define the standard unit of resistance ...
Since its discovery 100 years ago, our understanding of superconductivity has developed in a far from smooth fashion. Paul Michael Grant explains why this beautiful, elegant and profound phenomenon ...
In this video, Jonny Nelson explains resistance. The current through a component depends on both the resistance of the component and the potential difference across the component.
