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

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 ...

So we know from a previous video that electricity is the flow of electrons between atoms. These electrons can move about randomly. So we use voltage to push the electrons around a circuit. And when we ...

DigiKey has introduced an online configuration tool that allows engineers and system designers to create power supply ...

A steady supply of voltage is important in industrial and commercial applications to maintain equipment performance, product quality, and safety, while also minimizing downtime. Voltage sags (where ...

Electric cars are slowly, but surely becoming commonplace, and they introduce a whole new generation of specifications that are worth caring about. Range is an obvious one — but there’s another metric ...

With the advent of the electric era comes an entirely new lexicon for the automotive enthusiast to familiarize themselves with—kilowatt-hours, MPGe, SAE J1772—but few seem as poorly understood or as ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

The Chevy Equinox EV is one of the most important new vehicles in General Motors’ lineup. Before the reborn Bolt EUV arrives next year, this crossover will be the cheapest electric vehicle the ...
