Question

How does the resistivity of a metal change with an increase in temperature?

Options

• Resistivity decreases with increasing temperature

• Resistivity remains constant regardless of temperature change

• Resistivity becomes zero at high temperatures

• Resistivity increases with increasing temperature

Answer 1

In metals, resistivity generally increases with an increase in temperature. This is an important trend that distinguishes the temperature dependence of conductors from that of semiconductors, which show the opposite behavior.
