If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

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 ...

Contact resistance, or CRES, is one of those problems that most engineers prefer not to think about until it’s staring them in the face. For years, it could be managed quietly with routine probe card ...

You might think the probes in the picture are just funny looking alligator clips. But if you watch [tomtektest’s] recent video, you’ll learn they are really Kelvin probes. Kelvin probes are a special ...

Don�t heap all the blame for a wrong measurement on the DMM. There can be several less obvious sources of the errors. Testing assemblies and components usually includes checking the continuity of ...

Insulation failure is the root cause of many electrical conductors and equipment failures. When insulation fails, not only can equipment be damaged, but fire and shock can also result. Ideally, when ...

The high-performance semiconductor devices powering smartphone displays, AI computing, EV batteries and more are increasingly incorporating 2D materials to overcome silicon's scaling limits. To ...

The majority of metal traces used to produce electrical connections in semiconductor devices begin life as blanket metal films that are later patterned and etched to create conductive connections ...
