Electrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.
16 sty 2019 · This is a table of the electrical resistivity and electrical conductivity of several materials. Included are metals, elements, water, and insulators. Electrical resistivity, represented by the Greek letter ρ (rho), is a measure of how strongly a material opposes the flow of electric current.
Explore a comprehensive collection of tables and charts providing electrical conductivity data for a wide spectrum of materials including metals, polymers, ceramics, and more.
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/m2) E = electric field strength (volts/m)
The electrical conductivity values in this table are approximate and can vary depending on factors such as temperature, pressure, and impurities in the materials. Explore a curated list of electrical conductivity values for common materials in Siemens per meter (S/m) unit.
This calculator can be used to calculate electrical resistance of a conductor. Resistivity Coefficient (ohm m) (default value for copper) Cross sectional area of the conductor (mm2) - AWG Wire Gauge. 1) Note! - the resistivity depends strongly on the presence of impurities in the material.
