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 ...

Portable 3D optical inspection with 4Di InSpec transforms surface metrology, enhancing defect detection and quality assurance ...

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 ...

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 ...

Let's start with DC voltage, one of the simplest and most-used multimeter measurements. The DC voltage measurement is used to determine the difference in electrical potential between two points in a ...

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 ...

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 ...

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 ...

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 ...

The study of pavement skid resistance and surface texture analysis is central to understanding road safety and the longevity of asphalt pavements. At its core, skid resistance represents the ...

The measurement technique of the aspheric surface is mainly for the surface form and parameters. The surface form is the three-dimensional distribution of the surface in the spatial domain. The ...
