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 ...

Designers often use a current shunt to measure low current being sourced out of their power supply since many of today’s power supplies do not offer adequate accuracy from their built-in measurement ...

Washington State University researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. The team used a probe originally developed to ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

Texas Instruments tells us that Battery-monitoring systems are used to estimate state of health (SOH) and state of charge (SOC), especially in Electric Vehicles (EVs). To get detailed information ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...

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 ...

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 ...
