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

frequencies. In normal basic telephone service‚ a pair of wires is used for communication. But in case of mobile/wireless communications‚ airwaves are used instead of wires. These spectrum/airwaves are licensed by the Government. It is allocated in Mega Hertz (MHz) in telecom licenses. 4.2 MHz is given as start-up spectrum‚ which is topped up by 1.8 MHz to make it 6 MHz (4.2 + 1.8 MHz)‚ and so on. 2) Why spectrum is called a scarce national resource? Worldwide different frequencies are used for different
