Question: How do you measure inductor current? Answer: Switched-mode power supplies commonly use inductors to temporarily store energy. In the evaluation of these power supplies, it’s often useful to ...

Cool and accurate: An NPL researcher standing over one of their cryogenic current comparators. (Courtesy: NPL) Researchers in the UK have produced the most accurate cryogenic current comparator – a ...

The monitoring of current and power is more important than ever. Industrial automation, instrumentation, solar power conversion, battery monitoring, and medical measurement systems measure and log ...

Current sensing is used to perform two essential circuit functions. First, it measures “how much” current is flowing in a circuit; information that may be used for power management in a DC/DC power ...

As more systems become electrified, thermal management has turned into one of the “hottest” issues facing designers. Using current measurements for thermal management is a leading indicator of system ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy. And ...

Physicists have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external ...

Increasingly complex matrices of potential stray-current corrosion sources have made mitigation of potential problems both more difficult and more important. New techniques that use new hardware and ...
