resistivity

(ˌriːzɪsˈtɪvɪtɪ)
n
1. (General Physics) the 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 ohms. Symbol: ρ Former name: specific resistance
2. the power or capacity to resist; resistance

In terms of equipment type, geophysical equipment market is categorized into electrical resistivity, electromagnetic, seismic and others.
A noticeable decrease of the electrical resistivity upon CB addition was detected, and nanocomposite with a CB amount of 4 wt% revealed also a noticeable heating capability by Joule effect above 100 V.
Limited attempts have been made by researchers to explore the phenomenon of electrical resistivity in soils and its relationship with other soil properties; such as thermal resistivity, salinity, ground water distributions using four probe methods (Abu-Hassanein et al., 1996).
LCR Meter of Wayne Kerr Precision Component Analyzer Model 6440B was used to measure the dielectric properties at room temperature in the frequency range from 20Hz to 3MHz and DC electrical resistivity from room temperature to 300 AdegC for all the sintered pallets by two probe methods.
The comparison of these geophysical results reveals clear coherence between the SP negatives anomalies and the observed values of apparent electrical resistivity. On profile 1 (Figures 4 and 12), for example, one can easily notice that the negative, strong, and high anomalies peaks (-120 to -150 mV) of the spontaneous potential localized between 77.5 and 97.5 m correspond to the deeper conductive anomalies (around 350 Ohm.m) on the apparent electrical resistivity pseudo-section (marked by black contours), while on profile 2 (Figures 5 and 13) at depth of 21.83 m one can also see that SP value shows only negative maxima and minima and corresponds also to conductive anomalies on the apparent resistivity pseudo-section.
So a simple and inexpensive experiment consisting in the determination of the effective magnetic susceptibility and in the contactless measurement of electrical resistivity is described below.
At present, studies in China and elsewhere have mainly focused on electrical resistivity and dielectric constant of coal and rock.
First, to evaluate the ground freezing based on the electrical resistivity characteristics, two holes were bored at 3 m distance from the freezing pipe for the tomography tests prior to the freezing pipe installation.
Soil electrical resistivity testing has been gaining importance in geotechnical and geoenvironmental fields due to its time efficiency and cost.
On the other hand, the gold can form an appropriate barrier between copper and silicon, because it may penetrate through the silicon without reacting with it and presents a low electrical resistivity 2.35 [micro][ohm]cm [6] for ohmic contacts.
