E is the magnitude of the electrical field in the material (V/m), J is the magnitude of the electric current density in the material (A/m 2). If the electrical field (E) through a material is very large and the flow of current (J) very small, it means that the material has a high resistivity.
Thermal conductivity of gases, insulation products, aluminum, asphalt, brass, copper, steel and other common materials. Thermal conductivity is a material property describing the ability to conduct heat. Thermal conductivity units is W/(m K) in the SI system and Btu/(hr ft Â°F) in the Imperial system. Thermal Conductivity. - k -.
