Resistance is measured using what unit of temperature?
- Absolute.
- Centigrade.
- Fahrenheit.
Explanation from PART66Online
The temperature coefficient of resistance is conventionally expressed per degree Centigrade, relating how a material's resistance changes for each degree Celsius of temperature change. The Celsius scale is the standard reference used for these resistance-temperature relationships.

* Absolute (Kelvin) is used in thermodynamics
* Fahrenheit is not used in electrical resistance standards
* Centigrade is the practical engineering reference point for resistance temperature coefficients

The correct option is B. The temperature coefficient of resistance is normally tabulated per degree Centigrade, with the reference point taken at 20 degrees Celsius. Refer to Module 3.7 resistance and resistors for the standard R equals R nought times one plus alpha times delta T relation.
