Question

26. Explain increase in resistivity of a metal with
increase in temperature.
(2017)​

Answer 1

Answer:

When we increases the temperature the amplitude of vibration of atoms increases as result of which the number of collision among the electrons and atom increases, and hence resistances increases.

Answer 2

Answer:

The resistivity of conductors increases with rise in temperature. As the temperature of the conductor increases, the average speed of the electrons acting as the current carriers increases.
