Power Systems Which statement is not correct for the transmission line parameter R, L, G and C G = I/R. R is the AC resistance per unit length of conductor C. The line parameter R,L,G and C are uniformly distributed along the entire length of the line C. For each line, the conductors are characterized by σ c, μ c, εo = ε c and the homog At high frequencies at which most of communication system operate the internal inductance of the conductor is neglected.
