Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

This very subject came up recently in the Audioholics forum and I would like to expand on this subject further, but before I do I think it's important to go into the history of how this specification ...

From DIY levitation tricks to clever braking systems, these swirling paths of electrons keep finding new ways to surprise and inspire.

Editor’s note: A little while ago we published Part 1and Part 3 of this three-part series is also published. The fundamentals to translating the analog world into the digital domain reduces to a ...

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

When compared to “conventional” voltage, current, impedance, power, and spectrum tests spanning dc to RF, the world of wet-lab electrochemistry and its amperometric, voltammetric, and impedance ...
