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 ...

Measuring the electrical resistance (ohms) of motors, compressors, and other electrical devices in HVAC systems may seem straightforward. But when the measurements of zero (0) or “OL” (overload) come ...

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 ...

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 ...

As we said last month, electrical theory underlies everything we do in the electrical construction business. It is therefore necessary to review this theory regularly. We continue now with Ohm's Law.

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 ...

Megger now offers a digital low resistance ohmmeter that can deliver reliable results when using long test leads. The DLRO2, a 2 Amp handheld tester, is ideal for use in production line testing and ...
