Homework Help: Coaxial Cable and dielectric

  1. Apr 2, 2010 #1
    1. The problem statement, all variables and given/known data

    If I have two co axial conductors at V = 0 and the dielectric has a free charge density. Is that physically possible?

    2. Relevant equations

    No relevant equations

    3. The attempt at a solution

    I am not sure if you can have free charge density in a dielelctric when both conductors are at 0 potential.

    I think that if a dielectric has a free charge density, then it will conduct, i.e, it won't be a dielectric but a conductor.
