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 ...

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 application note describes the use of current-sense amplifiers, differential amplifiers, and instrumentation amplifiers to measure battery charge and discharge currents in smartphones, tablets, ...

The demand to increase energy efficiency in electrical products is driving the development of more accurate measurement instruments. Modern instruments now can quantify incremental gains made as ...

Trinamic Motion Control's TMCM-0013-xA current-sense boards are lab tools designed to simplify the measurement and visualization of two-phase motor currents. The boards are well-suited for tuning a ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors. Now in Part 3, we will take an in-depth look at electrical measurements. It is impossible to discuss ...
