Doubt regarding Transit time in electro magnetics

  1. Mar 11, 2013 #1
    Hello PF,
    I was watching a video from NPTEL (transmission lines), where the professor was explaining transit time. Ok now my doubt is that is the transit time delay in transmission lines due to distributed capacitors and inductors alone. Do resistors contribute to delay. For a propagation through long cable even if L and C are not present delay must be there, right?

    So transit time delay is a function of conductor property (R,L,C) + length of cable. Is it right?

    Another doubt is if ideal conductor is used will there be delay, theoretically? ie if R=0 and no L and C, will there be delay in a long cable?

    There is always L and C for any transmission line - even an infinitely thin, infinitely conducting pair of cables.
