The temperature coefficient of resistivity is a quantity that is:
A)always positive.
B)always non-negative.
C)sometimes negative.
D)represented by the symbol s.

Question

Quizplus · Accepted Answer

The temperature coefficient of resistivity can be negative for some materials, meaning that their resistance decreases as the temperature increases. Therefore, option A and B are incorrect. Option D is also incorrect as the symbol for the temperature coefficient of resistivity is usually denoted by the Greek letter alpha (α), not s.
