While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

At one time a relatively infrequent occurrence, voltage drop is now a major impediment to reliability at advanced nodes. Decades ago, voltage drop was only an issue for very large and high-speed ...

As a fundamental concept of electronic design, voltage drop ranks highly as one to understand well. I particularly appreciate when industry folks come up with creative ways to get the point across.

Electrical equipment that operates below its voltage rating can overheat or power down. Here's how to determine your load's operating voltage. Voltage drop across switchgear and feeder and branch ...

Inevitably, industrial facilities are going to have 460VAC, 3-phase motor loads. And, of course, since voltage drop is considered mainly a performance issue, maximum voltage drop rules on a circuit ...

In the first part of this electrical troubleshooting series, we discussed how a consistent approach to electrical troubleshooting can help HVAC technicians get a comprehensive assessment of what is ...

What type of equipment is best to use for low-voltage test of battery cells? What is an electronic load, and how does it work? How to overcome a major limitation with the low-voltage-discharge test.
