WHY

 Why are you writing this tutorial?

I am writing this tutorial as a "brain dump", and perhaps as a reference to my self. The tutorial is an exploration or study of electrical and electronic topics, and the information is available in the public domain. This tutorial does not have an editor other than myself, and is not verified by any other; thus it an informal work.

Is this tutorial accurate?

This tutorial is accurate to my knowledge. I do not take any liability for any inaccuracy that may be found. However, I would appreciate greatly if you point out any error.

What is unique about this tutorial?

I have tried to look for "gut level" or physical level answers whenever possible. I have tried to ask and answer the obvious, the basic, and the unconventional queries. My focus is to answer the essential or the conventional questions first. The explorative questions have been asked by not always answered.

Why have you chosen the dialogue form?

Dialogue form is a classic form to convey a subject. It focuses the discussion, provides continuity, and indicates clear landmarks when discussion shifts to different areas. At the same time, it enables us to handle all the million questions that crowd our mind when we begin studying a subject.

How did you chose the subject area or topic?

I studied electrical engineering, and I wanted to summarize the fundamentals from a personal understanding. First, I investigated the basics. Then, I incorporated topics for completion sake. I wanted the topics to cover the fundamental conceptual areas of electrical and electronic engineering.

How did you arrive at the answers?

I did not. Others did, and much of the knowledge is in the public domain. The principal task of mine is in filtering, reorganizing, and exploring different angles of the subject areas.

Lets focus on the subject at hand. Is electrical and electronic engineering a science?

Engineering and doing science are related but distinct activities. Engineering primarily deals with improving or designing a useful product. Science investigates nature, adds to our understanding of the nature, and thus enables or aids engineering.
