In this chapter we will extend the concepts which have been presented in the preceding chapter so as to develop general methods of phasor analysis for circuits which are under conditions of sinusoidal steady-state excitation. The methods are very similar to those for resistance circuits which were presented in Chap.2

In this chapter we will introduce an important frequency is that network function or parameter reaches a maximum value. In certain simple a networks, this occurs when an impedance or admittance is purely real-a condition known as resonance

In this chapter we shall show how the phasor methods developed to analyze circuits operating under sinusoidal steady- state conditions can be applied to the study of three-phase ac circuits

In this chapter we continue our introduction to circuit analysis by studying periodic functions in both the time and frequency domains. Any periodic function may be represented as the sum of an infinite number of sine and cosine functions which are harmonically related. The response of the linear network to the general periodic forcing function may be obtained by superposing the partial responses

In this chapter we first introduce some of the basic definitions most often used in network graph theory and then implement some of the results of introductory graph theory to obtain general laws (KCL and KVL) which apply to any network

In the chapter we shall present an introduction to nonlinear circuit analysis and shall examine a few interesting examples of that are used in practice. The principle of analysis will be emphasized. Graphical solution techniques will be given first. In addition, the basic concept of the phase plane shall be considered
