प्रश्न

How does the resistance of a pure metal change if its temperature decreases?

Advertisements

उत्तर

The resistance of all pure metals increases on raising the temperature and decreases on lowering the temperature. Therefore, the resistance of a pure metal will decrease on decreasing the temperature.
