Resistivity - Meaning, Definition & English Examples

Resistivity is a material's inherent property that measures its opposition to electric current. It quantifies how strongly a substance resists the flow of electricity, independent of its size or shape.

resistivity

/rɪˌzɪsˈtɪvəti/ /rɪˌzɪsˈtɪvɪti/

Definition:

A material's inherent opposition to the flow of electric current, measured in ohm-meters.

Synonyms:

resistance, impedance, reluctance

Part of Speech:

noun

Antonyms:

conductivity, conductance

Common Collocations:

electrical resistivity, resistivity measurement, high resistivity, low resistivity

Derivatives:

resistive, resistor

Usage Tips:

Use "resistivity" when discussing a material's intrinsic electrical resistance properties, not external factors like size or shape.

Common Phrases:

resistivity coefficient, thermal resistivity, soil resistivity

Etymology:

Derived from "resistive," from Latin "resistere" (to resist), combined with "-ity" denoting a state or quality.

Examples:

  • 1. Copper has low resistivity, making it ideal for wiring.
  • 2. The resistivity of rubber prevents electric current from passing through easily.
  • 3. Scientists measure soil resistivity to assess its electrical properties.
  • 4. Higher temperatures can increase a material's resistivity.
