Theory: The mathematical relationship between the electric field and the electric potential or voltage is observable in the lab threw reading and data plotting. With knowledge of the voltage everywhere, one knows the electric field everywhere. An easy way to describe the voltage is to indicate areas where the voltage or electric potential is a constant. These surfaces can be described as equipotential surfaces. This convenient method of detecting the electric potential in this way is that the electric field is perpendicular, or a normal, to the equipotential surfaces. By the nature, there is no force along the equipotential surfaces. Eqiupotentials can be mathematically mapped by: lEl = ldVl ldzl Procedure: 1. Place a conducting paper with a field map onto a mounting board
