The electrical resistivity of cytoplasm

open access: yesBiophysical Journal, 1976
The apparent cytoplasmic resistivity of two different giant cells has been measured using an extension of a previously developed single microelectrode technique. Each cell is penetrated by a metal microelectrode whose complex impedance is measured as a function of frequency between 500 kHz and 5.7 MHz.

The Measurement of Electrical Resistance [PDF]

open access: yesNature, 1894
Abstract In the present state of electrical science, the determination of the electric resistance of a conductor may be considered as the cardinal operation in electricity, in the same sense that the determination of weight is the cardinal operation in chemistry.

Effect of Chloride on Electrical Resistivity in Carbonated and Non-Carbonated Concrete

open access: yesApplied Sciences, 2020
The resistivity of a concrete structure exposed to chloride ions indicates the risk of early corrosion damage, because a low resistivity is related to rapid chloride penetration and to a high corrosion rate. Concrete resistivity is a geometry-independent
