Table of Electrical Resistivity and Conductivity

2019/6/27Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a material conducts an electric current. Electric conductivity may be represented by the Greek letter σ (sigma), κ (kappa), or γ (gamma).

Electrical resistivity and conductivity

The good electrical conductivity of plasmas makes their electric fields very small. This results in the important concept of quasineutrality, which says the density of negative charges is approximately equal to the density of positive charges over large volumes of the plasma ( n e = Z n i ), but on the scale of the Debye length there can be charge imbalance.

Electrical Conductivity of Elements and other Materials

Electrical conductivity is defined as the ratio of the current density to the electric field strength and can be expressed as σ = J / E (1) where σ = electrical conductivity (1/ohms m, 1/Ω m, siemens/m, S/m, mho/m) J = current density (amps/m 2)
