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 have studied a first-order circuit – namely, the RL Circuit – in great detail and used it to bring out all the important concepts in the ...
