(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) For all signal-chain devices to operate properly, each requires a stable-voltage power ...

Power MOSFETs (Metal-Oxide Semiconductor Field Effect Transistors) are three-terminal silicon devices that function by applying a signal to the gate that controls current conduction between source and ...

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

The power supply circuit is a ubiquitous component in all electronic devices, regardless of whether they are powered by batteries or by direct or alternating external electricity. The whole ...

Battery input (portable equipment) - Because of the size and weight restrictions of portable equipment, this power-management subsystem is usually integrated with the rest of the electronic system.

Have you ever wondered whether your USB ports are really delivering maximum power? There are several ways to find out. Windows offers you built-in functions to check the performance of your USB ports.

Editor’s note: This article is part of our roundup of USB-C battery packs. The simplest way to discuss electrical power is in units of volts (V), current measured in amperes or amps (A), and watts (W) ...

If you are dealing with solar or battery power, you might want to have one of these little energy meters built by [Open Green Energy] around. The Arduino-based instrument measures DC voltage, current, ...
