3 Terms and definitions

The following terms and definitions apply to this document.

3.1 Volume resistance

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 ohm.

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 ohm·m.

3.3 Surface resistance

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 ohm.
