Scientists have developed a sensor for measuring the strength of electric fields, which is much smaller, simpler and less prone to distortion than comparable devices. TU Wien has developed a sensor ...

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 ...

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 ...

When EDN published its first issue in 1956, electrical measuring instruments looked a little different than they do today. Howard Skolnik, a former colleague and key analog mentor from my Burr-Brown ...

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 ...

When describing a new device designed to measure the brain's electrical activity after injury, Col. Dallas Hack cut through all the details to get straight to the point of why the Army needed another ...
