Metal Electrical Resistance Chart

Resistivity is commonly represented by the greek letter ρ.

Metal electrical resistance chart. The table below gives the resistivity figures for a variety of materials particularly metals used as electrical conduction. Electric conductivity may be represented by the greek letter σ sigma κ kappa or γ gamma. The resistivity figures are given for materials including copper silver gold aluminium brass and the like.

The atoms of metal elements are characterized by the presence of valence electrons which are electrons in the outer shell of an atom that are free to move about. The resistivity of semiconductors depends strongly on the presence of impurities in the material a fact which makes them useful in solid state electronics. Electrical conductivity in metals is a result of the movement of electrically charged particles.

Table of resistivity for common materials. Conductivity is a measure of how well a material conducts an electric current. In electronics and electromagnetism the electrical resistance of an object is a measure of its opposition to the flow of electric current the inverse quantity is electrical conductance and is the ease with which an electric current passes electrical resistance shares some conceptual parallels with the notion of mechanical friction the si unit of electrical resistance is the ohm while.
