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 ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of 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 ...

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 ...

German research institute ISC Konstanz has developed a new method to measure the contact resistance of solar cell interconnections made with electrically conductive adhesives (ECA). The proposed ...

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 ...

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

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 ...
