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