A low resistance surface conducting conductor electric cable comprising a plurality of layered elongated sheets (1) of electrical conducting material. Each sheet is individually insulated (2) and the cable includes an outer insulating layer (3). The resistance of the conductive sheets can be progressively reduced to superconductivity by increasing the conductive sheets to critical ratio of cable length to aggregate perimeter length of cross-sectional area of the conductive sheets. In an alternative embodiment (figure 2) the sheets are folded in a concertina-shaped manner. The invention makes uses of the discovery electric current is conduct over the surface of a conductor and is related to the electrical resistance, the resistivity, the length and the perimeter of the cross-sectional area of the conductor in the form: R= rho L/P, where R is the resistance of the conductor, rho is the resistivity of the electrical conducting material, and P is the perimeter of the cross-sectional area of the conductor.
