Power Factor (PF) is a measure of how a load draws power from the source. When the current phasor leads the voltage phasor, PF is leading and when the current phasor lags the voltage phasor, PF is ...

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

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.

In Part 1 of this two-part series, we explored PLC basics and voltage sag susceptibilities. In this segment, we present PLC voltage sag test results along with guidelines for making PLC systems more ...

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.

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...

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) ...
