Introduction
Overview
Many applications of electrical engineering require a knowledge of the behavior of voltages and currents in electronic
devices and within conductors. In many other situations it is not enough to understand the behavior the voltages and
currents in just the conductors and ponents, but also the influence of the voltage and current on surrounding
materials. In physics classes we learn that electric and ic fields extend beyond the electrical carriers within
a device. In electrical puter engineering the extension of the fields beyond electronic devices and wires can
have both beneficial and deleterious effects. Without fields we would not have such modern conveniences as cell

phones, television, or even the puter memory chip. On the other hand, unwanted field interactions can
cause reversible and irreversible degradation in almost all types of electrical engineering systems. mon example
of this type of degradation is evident when a telephone signal on one line leaks over to an adjacent line. This annoying
phenomenon is known as cross talk. The diagram in Fig. shows that the field from one line extends into the other.
In this chapter we examine some of the behavior of electric fields and electric flux. We use the flat panel display as
a motivating example for this study. We have chosen the flat panel display as an illustrative example because it shows
the ubiquitous nature of ics in current technology. Flat panel displays are expected to be the video
display technology of the future for replacing the curren
