  1. Not that it really matters, but the so-called p is the greek letter rho ;-)
    Which in this instance is the resistivity (“resistance coefficient”) of the material, so yes Jeroen Wiert Pluimers​​​​, it’s a material constant

  2. Sorry but you seem to be putting 2 ideas together.The diagram can be interpreted in DC form OR ac form but never together which is trying to be done. DC is pure V=IR and that’s it. If you want to Quote ac formula you can add power factor,cable resistance factor and phase difference.So the diagram seems to be putting forward one diagram and should have had 2.one for DC and one for ac.

  3. I am an electrical engineer and there seemed to be confusion on R i was trying to help. It appears you were trying to use R as the resistance of the cable only Which indeed has validity.
