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. At high frequencies at which most of communication system operate the internal inductance of the conductor is neglected. For each line, the conductors are characterized by σ c, μ c, εo = ε c and the homog The line parameter R,L,G and C are uniformly distributed along the entire length of the line C. 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. For each line, the conductors are characterized by σ c, μ c, εo = ε c and the homog The line parameter R,L,G and C are uniformly distributed along the entire length of the line C.
