resistivity Definition

re·sis·tiv·ity (rē′zis tivə tē, ri zis′-)

noun

  1. property of, capacity for, or tendency toward resistance
  2. Elec. resistance per unit of area or volume, measured in ohms per meter: the reciprocal of conductivity

resistivity Usage Examples

Preposition: of

material: This means the resistivity of a material will also change with temperature.

Converse of object

  • measure: We measured the in-plane resistivity of the metallic layer with the change of the organic overlayer.
  • have: Soils and clays will tend to hold ground water, so will have a lower resistivity than rock or stone.

Adjective modifier

  • electrical: I need to know the electrical resistivity of water resistivity.
  • thermal: The new cellulose insulation can both absorb and release water vapor without significant loss of thermal resistivity.
  • low: Silicon, with lower resistivity, also tends to operate at lower frequencies, in the ' Slow wave ' mode.
  • high: Plastics generally have high resistivities, allowing them to maintain static charges for long periods.
  • specific: There are also many contradictory suggestions as to why the specific contact resistivity is reduced and becomes ohmic after annealing.
  • apparent: It requires three air strips to yield a relative variation smaller than 1 % in the values of the apparent resistivity.

Modifies a noun

  • surveying: This is an opportunity to learn about resistivity surveying.
  • meter: Now follows a list of the resistivity meter readings: a table that is 8 entries wide by 14 entries deep.
  • survey: In fact the results from the resistivity survey indicate a feature running a few meters away to east of the accepted line.
  • measurement: Therefore resistivity measurement is really a measure of the amount of water held in the ground at a particular point.
  • imaging: Resistivity imaging uses an array of electrodes to measure apparent ground resistance.
  • plot: A road to the northwest is clearly visible on the resistivity plot.

Noun used with modifier

  • surface: Results can be particularly affected by surface wetting or contamination, which greatly reduce surface resistivity.
  • volume: Constantan An alloy of 40 % nickel and 60 % copper, with a high volume resistivity and almost negligible temperature coefficient.
  • sheet: Most samples exhibited a reduced sheet resistivity resultant from film curing over the duration of the test.
  • ground: The difference from the original readings proved a gradual increase in the ground resistivity.
  • contact: Electrical Resistivity: Non contact resistivity measurements using a unique double paired coil induction method.
