All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

In a world of tight timelines and ever-increasing performance requirements, it’s critical to create circuit designs right the first time; thus, engineers in the analog and mixed-signal industry often ...

Recently, researchers developed a non-invasive method combining electrical impedance tomography and extracellular voltage activation to evaluate drug effects on ion channels. The resulting printed ...

In a perfect world, electrical insulation would allow no current to flow through it. Unfortunately, several factors can — and will — result in the deterioration and ultimate failure of electrical ...

Download this article in PDF format. Proper wiring and probing/contacting are critical to making successful measurements. When testing cells or batteries, using good engineering practices is important ...

In the first part of this series on the highs and lows of resistance measurements, I discussed the basic principles for making two- and 4-wire resistance measurements for measuring resistances of less ...

In the upcoming NFPA 70E 2024 Edition, the inclusion of the phrase “at each point of work” and the relationship to absence of voltage testing has prompted questions regarding the use of Permanent ...

To ensure efficient operation and safety over time, the properties and materials of photovoltaic (PV) panels must undergo many electrical and mechanical tests. The document that dictates PV panel ...

For over a decade, thousands of users have deployed Permanent Electrical Safety Devices (PESDs) in order to reduce their risks in isolating electrical energy. This innovation greatly reduces the ...

In today’s advanced packages, however, resistance no longer resides primarily inside transistors or neatly bounded test ...
