释义 | resistivity[ ree-zis-tiv-i-tee ] / ˌri zɪsˈtɪv ɪ ti / nounthe power or property of resistance. Also called specific resistance. Electricity. the resistance between opposite faces of a one-centimeter cube of a given material; ratio of electric intensity to cross-sectional area; reciprocal of conductivity. Origin of resistivityFirst recorded in 1880–85; resistive + -ity Words nearby resistivityresistant, resistate, Resistencia, resistible, resistive, resistivity, resistless, resistor, resist printing, resit, Reşiţa Dictionary.com UnabridgedBased on the Random House Unabridged Dictionary, © Random House, Inc. 2020 Example sentences from the Web for resistivityBritish Dictionary definitions for resistivityresistivity / (ˌriːzɪsˈtɪvɪtɪ) / nounthe electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/l, where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohmsSymbol: ρ Former name: specific resistance the power or capacity to resist; resistance Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co.

It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters. The American Heritage® Science Dictionary Copyright © 2011. Published by Houghton Mifflin Harcourt Publishing Company. All rights reserved. |
