Question

8.The resistivity of a conductor increases with ​

Answer 1

Answer:

The general rule is resistivity increases with increasing temperature in conductors and decreases with increasing temperature in insulators. ... As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thus when temperature goes up, resistance goes up.
