Electric Field Analysis

Preface

Since my days as an undergraduate engineering student, I was used to hearing comments from students that field theory is one of the most difficult subjects in the undergraduate curriculum. Later on, as a teacher, I have experienced the fact that not many teachers volunteer to teach field theory for reasons known to them. Moreover, over two decades, I have been told by my students that field theory is taught mostly from a mathematical viewpoint, and the physical understanding of issues related to field theory is normally not discussed in the classes. In this context, my own view is that it is true that nobody has seen electric field. But it exists and many physical phenomena are dependent on the nature of the electric field distribution. ...
