Quick Launch. The Navy Individual Ready Reserve (IRR) is a force that consists of personnel who must fulfill their MSO under 10 U.S.C., 651, members fulfilling a service obligation incurred via contract, and those who have fulfilled their MSO but voluntarily remain in the IRR.
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.
In physics, thermal conductivity (often denoted k, Î», or Îº) is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier's Law for heat conduction. Heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. Correspondingly, materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. The thermal conductivity of a material may depend on temperature.
