Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...

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 ...

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 ...

Metrological institutes on a chip: Efforts like this one seek to bring cutting-edge measurement-science technology and expertise from national metrological institutes directly to users. (Courtesy: ...

Many types of equipment use ball bearings to minimize friction in rotating parts, including automobiles, bicycles, electric appliances, and industrial machinery. Ball bearings are ground to ensure a ...

As countries around the world strive to reduce their carbon footprints and seek sustainable energy resources, the solar energy industry has experienced significant growth. Among the diverse process ...

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 ...
