In this chapter, we will learn what electrical current is. We will delve deep inside the atom to understand the workhorse of electrical engineering, the electron. We will study the principle on which all electrical circuits work.
We will examine the structure of the semiconductor and how we, as engineers, make use of it. This will lead us, through the PN junction, to consider the major semiconductor devices we use in our everyday life.
The Main Operation of All Electrical Circuits
Before we delve into ...
