SUMMARY
The resistance measured from the side of a metal disk placed at the center of a circular pan filled with a resistive solution is calculated using the formula R = (p * ln(b/a)) / (2πL). Here, 'p' represents the resistivity of the solution, 'b' is the radius of the pan, 'a' is the radius of the disk, and 'L' is the height of the disk. The solution involves integrating the resistance of thin rings between the radii 'a' and 'b' to derive the total resistance.
