Technician A says that a rear-window defogger can self-regulate the current flow. Technician B says that as the temperature of the grid decreases, its resistance decreases, reducing current flow. Who is right?

Question

Quizplus · Accepted Answer

Technician A is correct because rear-window defoggers often have a self-regulating system that adjusts current flow based on temperature, ensuring they do not overheat. Technician B is incorrect because as the temperature increases, the resistance of the defogger grid typically increases, which would reduce current flow, not the other way around.
