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.
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.
