Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and numerous other ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment, such as a user monitoring current in solar cells, inverters, or storage batteries. These ...

The proliferation of hybrid electric vehicles (HEVs) and electric vehicles (EVs) has created a new dynamic in automotive designs. HEVs and EVs no longer operate off a traditional 12-V lead-acid ...

If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you could ...

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 ...

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 ...

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 ...

Historically, researchers impaled giant squid, snail, and frog axons with electrodes to study nerve function by measuring ion channels. Today, electrophysiologists have enhanced their ability to ...
