Bulk resistivity units
The SIunit of electrical resistivity is the ohm-meter(Ω⋅m). [1][2][3]For example, if a 1 m3solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. Electrical conductivity(or specific conductance) is the reciprocal of electrical … See more Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current, such as pure water which is an insulator. A … See more Relation between current density and electric current velocity Electric current is the ordered movement of electric charges.
