Introduction
The resistance test and the correlation calculation of the resistivity are the contents of the basic part of the electronic measurement technology measured by the voltage method and the current method.
The electrical properties of resistivity have a wide range of values, from most conductive metals to better insulating materials, over 30 orders of magnitude.
In the electrical conductor (metal, carbon, etc.) based on Ohm's law, it is suitable for measuring the instantaneous value of direct current or alternating current. Not
At the same frequency, measurements with alternating current may be affected by capacitive or inductive impedance. Therefore, existing national or international standards
DC current is often used to calculate the resistance of solid materials.
Most non-metallic materials, like plastics, are classified into polymers and ionic conductors. In the measurement, the flow of charge is determined by the application of certain
The field strength of the electric field is achieved. In addition to measuring current, there is also a charging current that is formed from a polarized material and/or an electrostatically charged material.
As the time changes, the measured current gradually becomes smaller and the resistance changes significantly. If you can observe this effect, at a certain charge
After the electrical time, the measurement is repeated by measuring the current with the opposite polarity and then averaging the values obtained twice.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Volume resistance volumeresistance
The ratio of the DC voltage (V) applied between the two surface (opposite faces) electrodes of the sample to the steady state current (A) between the two electrodes.
Note. The unit of volume resistance is Ω.
3.2
Volume resistivity
The ratio of DC electric field strength (V/m) to steady state current density (A/m2) in the material. In fact, it is equal to the body in the unit cube
The product resistance is measured by two opposite faces of the electrode.
Note 1. Volume resistivity is not applicable to heterogeneous materials with different electrical properties.
Note 2. The SI unit of volume resistivity is Ω·m.
3.3
Surface resistance surfaceresistance
The ratio of the DC voltage (V) applied to the steady state current (A) between the two electrodes on the same surface of the sample.
Note. The unit of surface resistance is Ω.
