16.1: Introduction
This section provides an overview of the contents of the chapter.
16.2: Electric Dipoles
Earlier we discussed, and calculated, the electric field of a dipole: two equal and opposite charges that are “close” to each other. (In this context, “close” means that the distance d between the two charges is much, much less than the distance of the field point P, the location where you are calculating the field.) Let’s now consider what happens to a dipole when it is placed in an external field.
16.3: Calculating Electric Fields of Charge Distributions
The charge distributions we have seen so far have been discrete: made up of individual point particles. This is in contrast with a continuous charge distribution, which has at least one nonzero dimension. If a charge distribution is continuous rather than discrete, we can generalize the definition of the electric field. We simply divide the charge into infinitesimal pieces and treat each piece as a point charge.
16.4: Calculating Electric Potential of Charge Distributions
This section describes how to calculate the electric potential for several common distributions of charge including the line segment, ring, disk, and infinite line.
16.5: Direct Calculation of Electrical Quantities from Charge Distributions (Summary)
16.6: Direct Calculation of Electrical Quantities from Charge Distributions (Exercises)
16.7: Direct Calculation of Electrical Quantities from Charge Distributions (Answers)
This section provides the answers to the odd-numbered conceptual questions and problems.
