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 ...

The NEC provides a recommendation on voltage drop for branch circuits in Informational Note No. 4 following 210.19(A). A similar recommendation for feeders exists in Informational Note No. 2 following ...

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.

Most engineers think that using a power supply is a pretty simple task. But as currents go up, keeping the correct voltage on the device under test (DUT) can become a challenge. As current flows ...

Voltage drop at advanced nodes is a deadly serious problem that has become unmanageable with the methodologies used by most chip designers today. This article will cover the reasons why power ...
