By increasing the temperature, the specific resistance of a conductor and a semiconductor
- increases for both
- decreases for both
- increases, decreases
- decreases, increases
Correct answer: increases, decreases
Solution
As temperature rises, the specific resistance of a conductor typically increases due to increased lattice vibrations that impede electron flow. In contrast, for semiconductors, higher temperatures provide more energy to electrons, allowing them to move more freely, which decreases their resistance.
