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 low resistivity indicates a material that readily allows electric current. Resistivity is commonly … See more Ideal case In an ideal case, cross-section and physical composition of the examined material are uniform across the sample, and the electric field and current density are both parallel … See more Relation between current density and electric current velocity Electric current is the ordered movement of electric charges. See more • A conductor such as a metal has high conductivity and a low resistivity. • An insulator like glass has low conductivity and a high resistivity. See more When analyzing the response of materials to alternating electric fields (dielectric spectroscopy), in applications such as electrical impedance tomography, it is convenient to replace resistivity with a complex quantity called impedivity (in analogy to See more Band theory simplified According to elementary quantum mechanics, an electron in an atom or crystal can only have certain precise energy levels; energies between these levels are impossible.
