Sentence examples for resistivity from inspiring English sources

It possesses good thermal conductivity, heat and shock resistance, and high electrical resistivity at elevated temperatures.

A strain changes the resistance because the length, area, and resistivity of the conductor change.

The equation for resistance, is often written as where ρ is the resistivity of the material and is simply 1/σJ.

In this case, the rock gives a low radioactivity reading, which suggests that it is sand; its resistivity is high, which suggests it is oil-bearing.

As the glove's wearer flexes his fingers, his movements can be followed by monitoring changes in the strips' resistivity.

Rather than approaching a well with a fixed drilling plan, companies can now use "measurement while drilling" (MWD) tools to determine the pressure, temperature, vibration and electrical resistivity (useful for inferring rock properties) of the well as they drill.

These values depend to some extent on temperature; therefore, in applications where the temperature is very different from room temperature, the proper values of resistivities must be used to calculate the resistance.

The electrical resistivities of the rare-earth metals vary from 25 to 131 microohms-cm (μΩ- cm), which fall into the middle of the electrical resistance values of the metallic elements.

The different electrical resistivities of rock formations cause anomalies that, when mapped, are interpreted to reflect underground geologic features.

The figure shows the conductivities σ (and the corresponding resistivities ρ = 1/σ) that are associated with some important materials in each of the three classes.

Table 2 lists the resistivities of certain materials at room temperature.
