Electric Circuits and Networks

INTRODUCTION

A circuit containing a single linear time-invariant capacitor and a linear time-invariant resistor, excited by a voltage source in series or a current source in parallel, will constitute a first-order LTI circuit. We studied a first-order circuit — namely, the RL Circuit — in detail and used it to bring out all the important concepts in the time-domain analysis of electrical circuits in the previous chapter. Hence, we will be able to move through simple RC circuits rather quickly in this chapter. That does not mean that RC circuits are less important in any sense compared to RL circuits. RL, RC and RLC circuits are the basic building blocks of electrical and electronic circuits and are equally important. It is only that we chose ...
