Question

Cause greater obstrution to flow of free electrons

Answer 1

$\huge\underline\mathfrak\pink{hola Mate}$

$<b>$This obstruction to the flow of electrons is called as the resistance of the conductor. If the temperature of the conductor is increased, the kinetic energy of vibrating atoms is increased, due to which the atoms start vibrating with higher amplitude.
