- In Fig. 24-13, consider a differential element consisting of a flat ring of radius R’ and radial width dR’. Its charge has magnitude
- in which (2πR’)(dR’) is the upper surface area of the ring.
- 24-9 Potential due to a Continuous Charge Distribution
- The net potential at P can be found by adding (via integration) the contributions of all the rings from R’=0 to R’= R:
- The contribution of this ring to the electric potential at P is:
