Part IV Electrostatics and electromagnetism

Part IV provides an introduction to electrical science in the form of two chapters, one dealing with electrostatics and the other with electromagnetism. These two chapters are essential reading for anyone lacking a formal background in electrical science. The first of the two chapters begins by explaining the nature of electric charge and how it is quantified, then describes the ways that it can be concentrated and stored in capacitors. The chapter also introduces the important concept of the electric dipole that exists where two charges of equal magnitude but opposite polarity are placed in close proximity to one another. In the second of the two chapters we examine the comparable phenomenon that occurs ...
