Definitions and Units Used for Describing Resistivity
The Electrical Resistance (R) is an electrical quantity that describes how a material or a series of material or a material section reduces the electric current flow through it.
Ohm‘s law states that a current (I) that runs through a conductor is proportional to the potential difference (V) which is inversely proportional to the resistance (R). Resistance is measured in ohms, symbolized by the Greek letter omega (Ω).
It is named after the German physicist Georg Simon Ohm (1784-1854), who studied the relationship between voltage, current and resistance.
The Volume Resistivity (ρ, rho) is a bulk property meaning that their value does not depend on the size or shape of a particular specimen.
Resistivity unitIt depends only on the material itself. The volume resistivity expresses the resistance per unit volume of a sample and is also called bulk resistivity or specific resistance. This term is commonly applied for material characterization and classification.
