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

(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 ...

Variable current will generate inductance, capacitance, and their related properties of inductive and capacitive reactance. Although there's no energy loss that directly results from these properties, ...

A voltage divider is a passive linear circuit used to create a voltage less than or equal to the input voltage. It is a conversion device composed of a high-voltage arm and a low-voltage arm. The ...

The electrical upgrade of the green carbon facility at the aluminum plant was complete. A myriad of programmable logic controllers (PLCs) and PC-based graphic user interface (GUI) systems replaced the ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...

Growing concerns about energy efficiency have led to the development of electronics with higher power density. In grid-connected and industrial applications, such as AC motor control, uninterruptible ...
