Question

Does the resistivity of the material vary with the temperature?​

Answer 1

Answer:

The general rule is resistivity increases with increasing temperature in conductors and decreases with increasing temperature in insulators. ... Thus when temperature goes up, resistance goes up. For some materials, resistivity is a linear function of temperature.
