The energy is transferred from a source of constant voltage \( V \) to a consumer by means of a long straight coaxial cable with negligible active resistance. The consumed current is \( I \). Find the energy flux through the cross section of the cable is \( V I / n^{3} \), then find the value of \( n \) . (The conductive sheath is supposed to be thin).
