CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis 3.1 Introduction The steady-state behavior of circuits energized by sinusoidal sources is an important area of study for several reasons. First‚ the generation‚ transmission‚ distribution‚ and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second‚ an understanding of sinusoidal behavior makes possible the prediction of circuit behavior when nonsinusoidal sources are used through the use of techniques
