Overview
Electrical conductivity in metals is a fundamental property that allows electric current to flow through materials. This property is primarily due to free electrons that can move easily within the metal structure. Understanding conductivity is essential for various applications, including electrical...
Key Terms
Example: Copper has high conductivity, making it ideal for electrical wiring.
Example: In metals, free electrons allow for efficient current flow.
Example: Silver has low resistivity, making it a good conductor.
Example: V = IR, where V is voltage, I is current, and R is resistance.
Example: Copper has a positive temperature coefficient, meaning its resistivity increases with temperature.
Example: Certain metals become superconductors when cooled below a critical temperature.
