To solve this problem, we need to understand how temperature affects the electrical resistance of conductors and semiconductors.$\\$• For conductors:$\\$As the temperature increases, the atoms in a conductor vibrate more vigorously. This increased vibration causes more frequent collisions between the conduction electrons and the atoms, which increases the resistance. Therefore, the resistance of conductors increases with temperature.$\\$• For semiconductors:$\\$Semiconductors have a different behavior. As the temperature increases, more electrons gain enough energy to jump from the valence band to the conduction band. This increase in charge carriers leads to a decrease in resistance. Therefore, the resistance of semiconductors decreases with temperature.$\\$Based on this understanding, the correct option is:$\\$Option 3: Increases for conductors but decreases for semiconductors.
