The maximum electric potential for a charged ring occurs at its circumference, but a mathematical circle lacks a well-defined surface and potential. For a ring with a finite small diameter, often referred to as a donut shape, it is possible to calculate its electric potential. While there may not be straightforward analytic formulas available, numerical approximations can be utilized to determine the potential at various points on the circumference. Understanding these calculations is essential for accurately assessing electric potential in practical applications. The discussion emphasizes the importance of the ring's geometry in determining electric potential.
