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 ...

Interpreting a data sheet for a static-control product requires a certain level of knowledge and experience. Often, you must wade through myriad specifications, test methods, and claims without fully ...

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 ...

Superconductivity is a fascinating phenomenon in which certain materials exhibit zero electrical resistance and expel magnetic fields below a characteristic temperature, known as the critical ...

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

This Application Note illustrates the power dissipation and thermal transfer through the semiconductor package using thermal resistance model, which is critical in considering thermal management to ...

IN a letter published in NATURE of July 13, 1899, the author communicated some of the results he had obtained in measuring the electrical resistance of the blood. These results showed that the average ...
