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 shall investigate some ways of characterizing two-port networks. Before we do this, we must consider some of the more general details that apply to all networks which have two port. In addition, we shall consider interconnec of two-

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 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 the chapter we shall develop a method for representing a sinusoidal forcing function or a sinusoidal response by a complex number called a phasor transform,or simply a phasor. By working with phasors we shall effect a truly remarkable simplification in the steady state sinusoidal analysis of general circuits

In the chapter we shall study the properties of second-order circuits, i.e., circuits containing two energy-storage elements. Such circuits will, in general, be characterized by second-order differential equations

In the chapter we shall introduce the study of circuits characterized by a single energy-storage element--a capacitor or a inductor. It will be shown that the equations describing such a circuit may be put in a form involving an unknown variable and its first derivative. Such an equation is referred to as a first-order differential equation, thus we shall refer to circuits which contain only a single energy-storage element as first-order circuits

Discovery of Benzene Isolated in 1825 by Michael Faraday who determined C: H ratio to be 1: 1. Synthesized in 1834 by Eilhard Mitscherlich who determined molecular formula to be C6H6

In the chapter we present resistive circuit analysis methods. The first is based on KCL and determines all the node-to-datum voltages in a given circuit and is known as node analysis. The second method, based on KVL, determines all loop current and is known as loop analysis. After discussing superposition, we will introduce Thevenin's and Norton's theorems
