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 ...

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 ...

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 ...

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 ...

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, ...

This application note focuses on current sensing amplifier used in power management of portable devices. It describes how to solve the problems of estimating remaining battery life and implementing ...
