Lecture 11 (Jan. 30, 2009): Chapter 24: Electric Potential (cont’d) Calculating the El. Potential from the El. Field The electric potential energy of a system of point charges Illustrative examples
Equipotential surfaces for some typical charge configurations: Note that electric field lines and equipotential surfaces are always perpendicular to each other. Reason: Displacement along an equipotential surface must be perpendicular to the electric force if there is to be zero work done by the electric force.

One can determine the electric potential from knowing the electric field, and vice versa: ; ; x y z V V V E E E x y z = - = - = - b a b a V V E dl - = r r g E V = -∇ r r “The electric field vector is the negative potential gradient”
An Isolated Conductor in an External Electric Field: The picture shows an uncharged conductor suspended in an external electric field. The free electrons in the conductor distribute themselves on the surface as shown, making the
