Question

Quizplus · Accepted Answer

A material whose resistance falls as its temperature increases is said to have a negative temperature coefficient of resistance. The word "resistivity" refers to the inherent property of a material to resist the flow of electric current. The word "resistance" specifically refers to the opposition that a material offers to the flow of current.
