resistivity

정의: In physics, electrical resistivity and electrical conductivity are two intrinsic properties of materials that measure a material's local, intrinsic ability to conduct electric current. They are reciprocals of each other, so each can be deduced from the other. They are usually numbers or scalar fields, but can be generalized to tensor quantities when the material is non-isotropic, or to complex quantities in the setting of time-varying currents.
