CHAPTER 3
CONDUCTORS AND DIELECTRICS
3.1 INTRODUCTION
Materials are generally classified as conductors and nonconductors based on their electrical properties. The electrical properties of these materials are discussed in this chapter to understand the concepts of current and current density. Nonconducting materials are known as insulators or dielectrics. The characteristics of dielectric materials such as permittivity, susceptibility, dielectric strength, and polarization are also explained. The concepts of boundary conditions for electrostatics at the interface of two different mediums are introduced.
In this chapter, the concept of determining the capacitance for parallel plate capacitor, parallel wire transmission line, coaxial cable, and ...
