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

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

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

I'm wondering what the generally accepted rules are about what the maximum draw on a motherboard's led connectors is. I'm thinking about hooking up 2-3 leds per function (hdd, pwr, etc) and want to ...

The war of the currents was fairly decisively won by AC. After all, whether you’ve got 110 V or 230 V coming out of your wall sockets, 50 Hz or 60 Hz, the whole world agrees that the frequency of ...

Both watts (W) and volt-amperes (VA) are units of measurement for electrical power. Watts refer to “real power,” while volt-amperes refer to “apparent power.” Usually, electronic products show one or ...

This is an overview of the destructive effects that voltage drive has on the performance of electrodynamic loudspeakers. A more comprehensive treatment of the subject can be found in the book ...

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 ...

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 ...

When an electric current passes through the body, it can cause three main effects: When it comes to current, DC becomes hazardous at around 130 milliamps (mA)—a seemingly small amount, especially ...

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 ...

The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative ...
