Homework Help: Resistance calculation

  1. Aug 21, 2015 #1

    I am wondering how to calculate the resistance for the current running in radial direction starting from the center of a circle?
    It seems there is a formula out there, and I would also like to know how to derive that formula..Thanks.

    Welcome to the PF.

    What is the context of the question? Is this for schoolwork? Or for a personal project maybe?

    What are the Relevant Equations? Do you know how to calculate the resistance of a rectangular block of material? :smile:
