Electrical conductivity is the ability to conduct electric current.
The electrical conductivity of different materials is different.
Electrical conductivity (σ ) = 1/ρ = l/RA.
ρ = Resistivity of a material.
R = Resistance of a material.
L = Length of a material.
A = Area of Cross-section of a material.
Electrical Conductivity in terms of current density and electric field.
J = σ E
σ = Electrical conductivity of a material.
J = Current Density.
E = Electric field intensity.
