Document Summary

We can obtain the integral of path i by simply substitute i with ii, and the result does not depend on path. Example equipotential surfaces of the electric field due to a point charge are concentric spherical surfaces with the charge at the origin: lines of force (electric field lines) are always directed normal to the equipotential surfaces. From the example of point charge we know that. In the limit ra , potential at a general point r = rb: Thus, the equipotential surface of point source field are concentric spheres. In a multiple charge distributed system, the potential can be obtained by using superposition:
