Electrical resistance

  1. Sep 30, 2009 #1
    1. The problem statement, all variables and given/known data
    this is not a homework question... i want to know density vs resistance

    2. Relevant equations
    R = ρl/a

    3. The attempt at a solution
    none so far

    Oh dear...the rho there is not density, but the resistivity of the material. It depends on the properties of the material.

    and the resisitvity of the material is depending on its own density?
