In its most general form, this lemma states that the vector current density is equal to the product of the conductivity tensor and the electric field, though this is reduced to J = σE ["jay equals sigma ee"] for an isotropic conductivity.
In its most general form, this lemma states that the vector current density is equal to the product of the conductivity tensor and the electric field, though this is reduced to J = σE ["jay equals sigma ee"] for an isotropic conductivity. This law was first promulgated in 1827's The Galvanic Circuit Investigated Mathematically and may be extended to ac circuits if the impedance rather than resistance is used. For ten points, identify the fundamental law of circuit theory, which is best known in the form V = IR.
