Worked Examples in Engineering Field Theory documents a lecture course given by the author to first-year students in the Department of Engineering in the University of Leicester. This book mainly focuses on the concepts of flux and potential. This text is divided in two parts; the first of which is devoted to explaining the concept of flux, whereas the second part encompasses the concept of potential. In discussing the concepts of flux and potential, this book explains the related theories, and then provides examples, related problems, and solutions to the problems. Some of the specific topics included are electric flux, flux function, electrical materials, electric potential, and conductive heat transfer. This publication will be invaluable to mathematics, engineering, and chemistry students and practitioners interested in studying the concepts of flux and potential.
