Electric Potential, Part 3

  • For a continuous charge distribution, V = Integral ( k dq / r), where the integral is over the charge distribution, and r is the distance from dq to the point where V is to be found.
  • In the lecture, examples are given, which show how to find the electric potential produced by a charged ring, a charged disk, and a finite line of charge.
