1. Chapter 24 Electric Potential
In this chapter we will define the electric potential ( symbol V ) associated with the electric force and accomplish the following tasks:
Calculate V if we know the corresponding electric field Calculate the electric field if we know the corresponding potential V Determine the potential V generated by a point charge Determine the potential V generated by a discreet charge distribution Determine the potential V generated by a continuous charge distribution Determine the electric potential energy U of a system of charges Define the notion of an equipotential surface Explore the geometric relationship between equipotential surfaces and electric field lines Explore the potential of a charged isolated conductor
