Question

Do resistivity of metal increases with increase in temperarure

Answer 1

yes the resistivity of metals increase with rise in temperature ...because when heat is supplied...the electron s gain more Kinetic energy and move more vigorously and collide more ....hence the current flowing through the metal experience more resistance....hope it helps you.... Please Mark as brainliest answer

Answer 2

Ciao,
as the temprature of the condctor increases the amplitude of vibration of the atoms in the lattice increases and hence,the probability of their collision with free electrons increases.and we can say that this gives a larger targetv,that is,the collision cross section of the atoms increasez with temprature .so thu reitivity alao increases qith increase of temp.
stay blessed
