1 Theory and Objective An electric field exerts a force on electrically charged objects. The potential difference between two different points is given by = = - b a ab b a l d E V V V a . This is the integral of the electric field and the different displacement. This is interesting because when a surface is constructed so that the electric field is perpendicular to the surface, then the potential difference between two points, any two points, will always be zero on the surface. This classifies the surface as an equipotential surface with constant voltage. We can manipulate this equipotential surface and use charged conductors to map electric field and equipotential lines. Part 2 Can you guess in advance what happens? Will the field lines pass through the bodies, or go around them, or what? In advance, based on the fundamental concepts involving electric field lines, one would expect them to go around the bodies, almost in a circular pattern, which points evenly spaced or distanced from the center of the body. This would create equipotential lines
