There are different methods to measure current. One method is to use a resistor across a current output and measure the voltage. The voltage across the resistor is measured using ohm's law: where I is ...

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 ...

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 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 first time I used a multimeter was in my younger years. I was really into remote-controlled cars—but you couldn't just buy one and start driving. You had to buy a kit and a controller separately ...

EVERETT, Wash., Dec. 4, 2017 /PRNewswire/ -- Troubleshooting electrical systems has traditionally required gaining access to metallic contact points so the test leads can make contact. And while ...

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 ...

As a system and application engineer, I’ve saved countless hours by automating measurements with software such as LabVIEW. Although I’ve used it to build measurement applications, I’ve started to ...

You can characterize a semiconductor device to be its own temperature sensor by using an accurate four-wire measurement technique. Semiconductor junctions — from the millions of transistors used in ...
