Definition

A measure of how strongly a material opposes the flow of electric current, typically expressed in ohm-meters.

Example

The resistivity of copper is much lower than that of rubber, making copper a better conductor of electricity.

Conversation

Have you ever heard of resistivity in materials science?

Yeah, it's about how much a material resists electric current, right?

Exactly! It’s interesting how different materials have different resistivity values.

For sure, it explains why some conduct electricity better than others.

Root Explanation

Resistivity is formed from "re-" (meaning again or back), "sistere" (meaning to stand), and the suffix "-ity" (meaning the state or condition of). The word describes the condition of a material's ability to resist the flow of electric current.

Memory Tip

Think of a material that 'stands against' ('sistere') the flow of electricity, with 're-' suggesting a return or resistance, and '-ity' indicating a state. This helps you remember that resistivity refers to the state of resisting electrical flow.
