Bulk Resistivity and Conductivity of Metals - Deringer Ney

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 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. • The conductivity of a semiconductor is generally intermediate, but varies widely under different conditions, such as … See more Even if the material's resistivity is known, calculating the resistance of something made from it may, in some cases, be much more complicated than the formula In cases like this, … See more Band theory simplified According to elementary quantum mechanics, an electron in an atom or crystal can only have certain precise energy levels; … See more Linear approximation The electrical resistivity of most materials changes with temperature.
