1. In the circuit shown in the Fig 3-15, it is desired that 23 2v, a)Find the value of R that gives the desired relationship. b) Suppose that v,=-10V and v2=10V, find the magnitude of the currents through all resistors and the powers dissipated by all resistors

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

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 the chapter, we first define mutual inductance and study the methods whereby its effects are included in the circuit equations. We conclude with a study of the important characteristics of a linear transformer and an important approximation to a good iron-core transformer which is known as an ideal transformer

In this chapter we will develop the concept of average power as distinguished from instantaneous power. We will also be concerned with apparent power, power factor, and complex power. By the way, we discuss the maximum amount of power transfer from the source to the load

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
