The standard unit of electric current, the ampere, is one of the seven base units in the International System of Units. But measuring a current exactly in amperes is not an easy task. In fact, in 1990 ...

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

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...

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 ...

Testing electrical systems for electrostatic discharge (ESD) robustness usually involves using IEC 61000-4-2 as a benchmark. This standard defines the stress current waveforms for each voltage level, ...

In the middle of a chilly October night in 2025, my two friends and I suited up at the Cottonwood Creek trailhead and started a trek into the Sangre de Cristo mountains of Colorado. It was a little ...

In this article learn about options for measuring current in motor control applications, the strengths and challenges of these options, and how using precision current measurement can optimize the ...
