• CURRENT

• RESISTIVITY

• CONDUCTIVITY

• RESISTANCE

The ratio of the magnitudes of electric field and current density. It is the measure of the ability of a material to oppose the flow of current.

• CURRENT

• RESISTIVITY

• CONDUCTIVITY

• RESISTANCE

The reciprocal of resistivity. It is an intrinsic property of a material which is defined as the measure of the amount of electrical current a material can carry. Its SI unit is (Ω . m)⁻¹
