Fundamentals of Electric Circuit Theory

Description

Electric circuit theory is one of the most vital aspects of electrical engineering. Understanding how components work individually and collectively is the basis for designing, manufacturing, and troubleshooting all kinds of electronic devices and systems. This article will cover the basic circuit components, laws, and parameters in electrical engineering. Electric circuits or networks are the assemblage of devices and or equipment needed to connect the source of energy to the user or the device which exploits it. Communications systems, computer systems and power systems all consist of more or less complicated electric circuits which themselves are made up of a number of circuit elements. Digital electronics are electronics systems that use digital signals. Digital electronics are representations of Boolean algebra and are used in computers, mobile phones, and other consumer products. In a digital circuit, a signal is represented in one of two states or logic levels. The advantages of digital techniques stem from the fact it is easier to get an electronic device to switch into one of two states, than to accurately reproduce a continuous range of values. It will be useful not only to students of physics, but to students of related disciplines like Electrical and Mechanical Engineering. With such a wide audience in kind, it includes in the opening chapter a presentation of the basic notions of electric circuits and transformers. The book contains a number of appendices that will be of interest to the relatively advanced students as well as to specialists.
