This article was originally published in March 2017 on the Residential Lighting website. Residential Lighting was the precursor to Furniture, Lighting & Decor. The magazine ran for 25 years and was a ...

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

The Potential Difference or Voltage Drop can be considered the voltage difference between any two points in a circuit. It is also the difference in electric potential between the final and the initial ...

When measuring current with a shunt resistor, what side of the load do you put it on? If you're amplfying the voltage drop across the sense resistor and digitizing that voltage, it makes a difference.

For an efficient design, the conductor ampacity tables in Chapter 3 of the National Electrical Code (NEC) provide a starting point. But did the installation stay efficient over time? One way to ...
