The resistance temperature coefficient is defined as
  • a)
    increase in resistance per degree centigrade
  • b)
    decrease in resistance per degree centigrade
  • c)
    the ratio of increase in resistance per degree centigrade to the resistance at OºC
  • d)
    the ratio of increase in resistance per degree centigrade to the rate of rise of resistance at OºC
Correct answer is option 'C'. Can you explain this answer?

The resistance-change factor per degree Celsius of temperature change is called the temperature coefficient of resistance. This factor is represented by the Greek lower-case letter “alpha” (α).
A positive coefficient for a material means that its resistance increases with an increase in temperature. Pure metals typically have positive temperature coefficients of resistance. Coefficients approaching zero can be obtained by alloying certain metals.
A negative coefficient for a material means that its resistance decreases with an increase in temperature. Semiconductor materials (carbon, silicon, germanium) typically have negative temperature coefficients of resistance.
