While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

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 ...

Most current meters used by scientists cost about $15,000 each, while Sheremet's meter is only about $500, and he makes each one by hand. It takes him about a week to build and calibrate 10 of them.

An atomic force microscope can be used as a single-electron current meter, according to new experiments by researchers at IBM. The technique, which measures the energy levels of single molecules on ...

Bipolar junction transistors transfera current from a lower-resistanceemitter to a higher-resistance collector.You can use this property to measureinductance by ...

[DainBramage] needed a DC ammeter to check how long his amateur radio station would be able to stay powered on battery backup power. The one’s he already had on hand were a Clamp Meter, which could ...

In India, “transmission losses” due to illegal connections or tampering consume up to 42% of total electricity production. (Source: BBC) Stealing electricity has been around since shortly after Thomas ...

Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...
