Doubt regarding Transit time in electro magnetics

Click For Summary
SUMMARY

The discussion centers on the concept of transit time delay in transmission lines, specifically questioning the contributions of resistors, inductors (L), and capacitors (C) to this delay. It is established that transit time delay is a function of the conductor properties (R, L, C) and the length of the cable. The consensus is that even in an ideal conductor scenario, where resistance (R) is zero and inductance (L) and capacitance (C) are absent, some delay will still occur due to the inherent properties of transmission lines.

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.
