Question

Why resistance of a metal increases as that of carbon decreases with rise in temperature. I mark it branliest answer for correct.

Answer 1

Answer:

bcoz carbon evaporates

Answer 2

hey mate your answer is here ⬇️⬇️⬇️

you heat a conductor, its constituent atoms get excited and start vibrating more. This means that the free electrons—the ones which give rise to the ‘current’ when there’s a potential difference between the ends of the conductor—collide more and more with the atoms in the conductor and get ‘hindered’. Thus, the conductor becomes more resistant to the flow of current through it.

On the other hand, if you cool a conductor, its atoms vibrate less, and the electrons find it easier to move, making the conductor less resistant

hope this will help you..
