Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...

We may receive a commission on purchases made from links. There's not a trade, job, or project in the world that wouldn't benefit from a bit of measurement before the work begins. Whether you're ...

A sensor designed to measure the strength of electric fields has been developed by TU Wien, who claim its creation is smaller, simpler and less prone to distortion than comparable devices. According ...

Most of the Hackaday community would never wire a power supply to a circuit without knowing the expected voltage and the required current. But our mechanical design is often more bodged. We meet folks ...
