FUNDAMENTALS OF ELECTRIC CIRCUITS

INTRODUCTION OF FUNDAMENTALS OF ELECTRIC CIRCUITS :

Electric circuit theory and electromagnetic theory are the tw o funda -mental theories upon which all branches of electrical engineering are
built. Many branches of electrical engineering, such as po wer, electric
machines, control, electronics, communications, and instrumentation, are based on electric circuit theory .

Therefore, the basic electric circuit theory course is the most important course for an electrical engineering student, and al ways an e xcellent starting point for a be ginning student in electrical engineering education. Circuit theory is also v aluable to students specializing in other branches of the ph ysical sciences because circuits are a good model for the study of energy systems in general, and because of the applied mathematics, physics, and topology involved.FUNDAMENTALS OF ELECTRIC CIRCUITS

In electrical engineering, we are often interested in communicating
or transferring energy from one point to another . To do this requires an
interconnection of electrical devices. Such interconnection is referred to
as an electric circuit, and each component of the circuit is kno wn as an
element.FUNDAMENTALS OF ELECTRIC CIRCUITS

A simple electric circuit It consists of three basic elements: a battery, a lamp, and connecting wires. Such a simple circuit can e xist by itself; it has se veral applications, such as a flashlight, a search light, and so forth. A complicated real circuit is displayed , representing the schematic diagram for a radio receiver. Although it seems complicated, this circuit can be analyzed using the techniques we co ver in this book Our goal in this text is to learn various analytical techniques and computer software applications for describing the behavior of a circuit like this.
