    In pure metals, resistance increases with rise in temperature.

    In alloys such as Gold, Silver and Germanium, the rise in temperature results in increased resistance but the resistance in alloys is relatively lower than in pure metals.

    Explanation:

    Resistivity increases with increasing temperature in conductors and decreases with increasing temperature in insulators.
