Hi,

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:
