(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.

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

I knew I was missing something important when as a mid-level electrical engineer, I used to wonder which voltage value I should be using in my calculations. Was it 110V, 115V, 117V, or 120V? Was it ...

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) ...

Electronic enthusiasts may be interested to know that Adafruit has announced the arrival and availability of its new Adafruit INA260 high or low side voltage, current, power sensor. Offering a small ...
