WebElectric Current is the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Electrons are minute particles that exist within the molecular structure of a substance. Sometimes, these electrons are tightly held, and other times they are loosely held. WebThe reciprocal of resistivity is called electrical conductivity. Electrical conductivity (σ) = 1 / ρ = 1 / RA = ne 2 τ / m. Its SI units is ohm -1 m -1 or mho m -1 or siemen m -1. Relation between current density (J) and electrical conductivity (σ) is given by. J = σ E. where, E = electric field intensity. 危ない木
