A long straight cable of length l is placed symmetrically along z - axis and has radius a(lt lt l) . The cable consists of a thin wire and a co-axial conducting tube. An alternating current thin wire and returns along the coaxial conducting tube. The induced electric field at a distance s from the wire inside the cable is vec(E )(s, t)=mu_(0)I_(0)v cos (2pi vt) ln ((s)/(a))hat(k) Compare the conduction current I_(0) with the displacement current I_(0)^(d) .
