Question: If the temperature of a metallic conductor increases, what happens to its resistivity?

Options:

Correct Answer: Increases

Solution:

For metals, resistivity increases with temperature due to increased lattice vibrations.

If the temperature of a metallic conductor increases, what happens to its resistivity?

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.

Resistivity and Temperature Relationship – As temperature increases, the resistivity of metallic conductors increases due to enhanced lattice vibrations that impede the flow of electrons.
