Power Systems The skin effect shows that

current density is more at the centre of the condutor
the distribution of AC current is uniform through the cross section of the conductor
current density is lower at the surface of the condutor
current density is more at the surface of the condutor

True
either 1 or 2
None of these
False

Power Systems Which statement is not correct for the transmission line parameter R, L, G and C

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.
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.
