Resistance between parallel wires in an insulator?

  1. Nov 28, 2012 #1
    Hi all,

    New here...I was wondering if anyone knows a formula to calculate the (insulation) resistance between two parallel conductors buried in an insulator. For example say 2 copper pins of 1mm diameter spaced 2mm apart over a 20mm length in a plastic (ptfe). The numbers/material are not specific to what I want to do just for example purposes.

    Any help would be great as I've seen stuff for concentric cylinders but nothing for parallel conductors.

    Would it be the same diffusion equation as for heat flow?
