What is the effect of increasing the temperature on the resistivity of semiconductors and metals?
Understand the Problem
The question asks how the resistivity of semiconductors and metals changes when their temperature is increased. Resistivity is a measure of how much a material opposes the flow of electric current. The question requires knowledge of the electrical properties of materials and how temperature affects them.
Answer
Metal resistivity increases with temperature. Semiconductor resistivity decreases with temperature.
The resistivity of metals generally increases with temperature. In contrast, the resistivity of semiconductors generally decreases with increasing temperature.
Answer for screen readers
The resistivity of metals generally increases with temperature. In contrast, the resistivity of semiconductors generally decreases with increasing temperature.
More Information
The temperature coefficient of resistance is positive for metals and negative for semiconductors.
Tips
It's important to remember that metals and semiconductors behave oppositely with respect to temperature changes and their effect on resistivity.
