In a uniform flux-flow state of a type-II superconductor, (i) the resistivity tensor {rho}{sub {ital i}{ital j}} is independent of the dissipative transport current density {bold J}{sup {ital T}}, and (ii) there exists a constraint on the relative orientation of {bold J}{sup {ital T}} and the average flux density {bold B}. These two simple general properties can already account for the Lorentz-force independence of the resistive transition in high-{ital T}{sub {ital c}} superconductors for the applied current in the {ital ab} plane, and the magnetic field making any not-too-small angle with this plane.
