Resistance Calculation in Radial Direction - Learn Formula

Click For Summary
To calculate the resistance of current flowing radially from the center of a circle, a specific formula is needed, which may involve the geometry of the circle and material properties. The discussion emphasizes the importance of understanding the context, whether for academic purposes or personal projects, to provide accurate guidance. Participants inquire about relevant equations, suggesting that knowledge of resistance calculations for different shapes, such as rectangular blocks, could be beneficial. Deriving the formula for radial resistance may require additional information about the material and dimensions involved. Understanding these concepts is crucial for accurately determining resistance in this scenario.

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:
