VR has various meanings in the Composition category. Discover the full forms, definitions, and usage contexts of VR in Composition.
The volume resistance between two electrodes of unit area and unit distance apart that are in contact with, or imbedded in, a specimen, is the ratio of the direct voltage applied to the electrodes to that portion of the current between them that is distributed through the volume of the specimen. Usually expressed in ohms/centimeter. The measure of ratio of the potential gradient parallel to the current in the material to the current in density.
