electrical resistivity

Electrical resistivity is a property of a material that measures how much it opposes the flow of electrical current. Think of it like friction for electricity: materials with high resistivity, like rubber or glass, prevent electricity from passing through easily, while materials with low resistivity, like copper or silver, allow electricity to flow more freely. Resistivity depends on the material's atomic structure and temperature. It helps in selecting materials for electrical wiring and devices, ensuring efficient and safe electrical conduction.
