A new technique for embedding atomic-scale wires within crystals of silicon has revealed that Ohm’s law can hold true for wires just four atoms thick and one atom tall. The result comes as a surprise ...

For more than a century, scientists have relied on separate tools to measure the three core building blocks of electricity: volts, ohms, and amps. Each describes a different piece of how electricity ...

A team of scientists has revealed how a single quantum device can accurately measure the three fundamental units of electricity—the ampere (unit of electrical current), the volt (unit of electrical ...
