## Power Systems For a lossy transmission line, the characteristic impedance does not depend on

The permittivity of the dielectric separating the conductor.
The conductivity of conductors.
The operating frequency of the line.

## Power Systems The characteristic impedance of a transmission line is

Directly proportional to its length.
Directly proportional to square root of its length.
Inversely proportional to square root of its length.
Independent of its length.

## Power Systems Which following statement are not true for line parameters R, L, G and C of transmission line

All of above.
LC = μ ε and RG = σ ε.
G = 1/R where G is conductance of line.
Both R and G depend on the conductivity of conductor forming the line.

## 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.
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
