Technician A says that resistance increases as the diameter of a conductor increases. Technician B says that resistance increases as the temperature of a conductor increases. Which technician is correct?

Question

Quizplus · Accepted Answer

Technician B is correct because resistance typically increases as the temperature of a conductor increases. This is due to the increased vibration of atoms at higher temperatures, which makes it more difficult for electrons to pass through the material. Technician A is incorrect because resistance decreases as the diameter of a conductor increases, given that a larger cross-sectional area allows more electrons to flow easily.
