Web16 Jan 2024 · Similarly, when the temperature rises, the electrons start moving rapidly which creates resistance to the flow of electricity in the conductor. As a result, the resistance increases. Similarly, when the temperature decreases, there is creation of less resistance to the electricity flow. As a result, the resistance will decrease.
