A simple and universal formulation for the transport V (I) curve is given for a superconducting cylinder of radius a with a power law E (J), E= (Ec Jc) ∫J Jc ∫n-1 J. This formulation is a function of Ec, Jc, n, a, and the current sweeping rate R. Concepts of the full penetration and the relevant voltage as well as several influencing factors in using this formulation are discussed. © 2007 American Institute of Physics.
