If the temperature of a metallic conductor increases, what happens to its resistivity?
Correct Answer: Resistivity increases
- Step 1: Understand what resistivity is. Resistivity is a property of a material that determines how much it resists the flow of electric current.
- Step 2: Know that metals are good conductors of electricity, meaning they have low resistivity.
- Step 3: Learn that temperature affects the behavior of atoms in a metal. When the temperature increases, the atoms in the metal vibrate more.
- Step 4: Realize that these increased vibrations make it harder for electric current to flow through the metal.
- Step 5: Conclude that as the temperature of the metallic conductor increases, its resistivity also increases.
