Gauss' Law Study Guide for Chapter 24 Outline 1. Electric Flux Electric flux represents the total number of electric field lines crossing through a surface. The basic equation for flux is F œ IE where is the magnitude of the electric field, and is the area of the surface. This equation I E only applies if the electric field has and is to the surface. constant magnitude perpendicular If the electric field is at an angle to the surface, the flux is E F ) œ œ IE E A cos where is the area vector (pointing perpendicular to the surface), and is the angle between A E ) and . In particular, the flux is zero if is parallel to the surface. A E If a surface has several parts, then you must add together the flux from each part. The most general formula for flux involves an integral of the electric field over the surface. 2. Gauss' Law Gauss's law states that the net electric flux out of a closed surface is proportional to the amount of charge inside: F F % out in œ U inside ! You may use Gauss's law on any closed surface,
