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 ...

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 ...

The boss picked you to design equipment to measure in-circuit resistances on circuit boards as they reach the end of a production line, and a colleague suggested you investigate six-wire measurements.

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...

Multiterminal Josephson junctions, nanoscale devices with unique electronic properties, comprise non-superconducting metallic material coupled to three or more superconducting leads. These devices ...

Maybe the most common applications for very-low-value resistors (i.e., milliohms (mΩ) and below) are current-controlling circuits, where their low value reduces power losses. For these applications, a ...

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 ...

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...

When working on electrical projects around the home—whether that’s troubleshooting an issue with your HVAC system, repairing an appliance, or testing a car battery—a multimeter is essential. These ...

Unconventional metal structures have begun popping up in integrated circuits (ICs) with increasing regularity, for a number of reasons. The growing demand for integrated cameras and image recognition ...
