The better the analog front-end for measuring battery current, the more accurately you'll be able to gauge the remaining run-time for your battery-backup system. Here's a discrete front-end design ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

Using a shunt is simple. Just select a shunt resistor of a known resistance, measure the voltage drop across the shunt, and use Ohm’s law to calculate the current. Designers often use a current shunt ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. Bob Zollo, Product Planner, Power and Energy Division, Keysight Technologies Efficient use of energy is a key factor in ...

To measure resistance, you usually have to take the resistor to be tested out of the circuit, and sometimes that’s impossible. If you’re using a multimeter, measuring very small resistances is ...

Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal ...
