Electric Circuits and Networks

INTRODUCTION

In this chapter, we study simple circuits containing one type of element – resistor or inductor or capacitor – driven by one independent source, either an independent voltage source or independent current source. These circuits may contain more than one element, but all of them will be of same type except the source. The aim of this study is to understand the nature and behaviour of each element type thoroughly. We will also deal with ‘series and parallel equivalents’ that can be used to replace series or parallel connection of multiple elements of same type by one equivalent element of that type. Moreover, we deal with two interesting source functions – unit impulse function δ(t) and unit step function u(t). These functions are ...
