उत्तर
If the temperature of a metallic conductor is increased, its electrical resistance increases. This happens because a rise in temperature causes the atoms or ions within the conductor to vibrate more vigorously, which increases the frequency of collisions with the flowing electrons and further obstructs the flow of electric current.
