Question

does the resistance if a metal change when we raise the temperature of the metal

​

Answer 1

The free electrons in a metal are in constant random motion. If the temperature of the metal is raised the atoms vibrate more strongly and the electrons make more violent collisions with them and so the resistance of the metal increase.

Answer 2

Answer:

➡️Yes, the resistance if a metal change when we raise the temperature of the metal.

➡️The free electrons in a metal are in constant random motion.
