Which of the following is the fractional change in resistance per kelvin?
Correct answer: D. Temperature coefficient of resistance
- A. Conductivity
- B. Resistivity
- C. Temperature coefficient of resistivity
- D. Temperature coefficient of resistance
Explanation
The temperature coefficient of resistance represents how the resistance of a conductor changes with temperature. It is defined as the fractional change in resistance per Kelvin.

About Temperature Coefficient of Resistivity
Temperature coefficient of resistivity describes how a material's resistivity changes for each degree change in temperature. Questions use the relation between resistance, temperature and the coefficient, especially for metallic conductors with positive values and semiconductors with negative values. Resistivity is a material property, unlike resistance, which also depends on dimensions.
