## Electromagnetic fieldsThis revised edition provides patient guidance in its clear and organized presentation of problems. It is rich in variety, large in number and provides very careful treatment of relativity. One outstanding feature is the inclusion of simple, standard examples demonstrated in different methods that will allow students to enhance and understand their calculating abilities. There are over 145 worked examples; virtually all of the standard problems are included. |

In Figure 10-15, we illustrate a capacitor of total free charge Qf with a

between the plates in (a) and with a dielectric completely filling the region

between the plates in (b). The directions of the various field vectors are also

shown.
