Static Fields and Potentials describes two of the fundamental interactions in nature: gravity and electromagnetism. The book introduces the associated fields, potentials, and energies and explains the relationship among them. It shows how these interactions manifest themselves in different ways, from the formation of stars to the operation of thunderstorms. The book also demonstrates how they are harnessed technologically in applications, such as hydroelectricity, electrical circuitry, and DNA finger-printing.To do this, we consider first what the resistance of the wire needs to be. ...
