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. |

... charge density in a l.i.h. dielectric can always be written as Ρ = Pf Ke = Рь - Ke 1 ( 10-59 ) which shows us that the total charge density is always less than the free charge density since k > 1. As a special case , we see that if e ...
