SUMMARY
The voltage difference between two surfaces can be determined by integrating the electric field (E) across the surfaces of a capacitor. Given the charge density (sigma) and the radii of the inner (r1) and outer (r2) surfaces, the Poisson equation can be solved to find the voltage difference. However, directly integrating the electric field may provide a simpler solution in this scenario.
