ABSTRACT
This chapter reviews three fundamental laws of physics and electrical engineering, namely Ohm’s law, Kirchhoff’s voltage law, and Kirchhoff’s current law. These three laws are instrumental in performing basic circuit analysis. Laws serve a vital purpose in electrical engineering analysis and problem-solving in DC as well as AC domains. In addition to the basic laws, important electrical circuit principles and circuit simplification techniques, such as voltage division and current division and their application will be illustrated through sample problems. The chapter introduces the reader to two basic electronic devices, namely a diode and a transistor, their basic characteristics, and some of their applications. Voltage division is a shortcut for the determination of voltage across a series resistor. The chapter provides a brief introduction to a common printed circuit board (PCB) and an assortment of common electronic devices typically installed on a PCB to perform control, monitoring, and data collection functions.
