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

In high voltage applications involving tens of thousands of volts, too often people think about the high voltage needed but don’t consider the current. This is especially so when part of the circuit ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

The LT1991/5/6 gain-selectable amplifier chips by Linear Technology (Reference 1) can be configured into either inverting, non-inverting, or difference amplifiers. Their integrated, precisely matched ...

Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

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 ...

The ever-changing properties during cell charging. The impact of wire-path resistance. Dealing with charger inefficiencies. When lithium-ion cell testers are being specified, the request is for a ...
