This lecture covers the analysis of AC circuits focusing on impedance, admittance, and phasors. The instructor explains mesh analysis, AC circuit analysis, periodic functions, and the importance of AC circuits. The lecture also delves into the sinusoidal quantities, mean value, RMS value, and angular frequency. Furthermore, it discusses the heating of a resistor, phase difference, and the response of a linear circuit to a sinusoidal excitation. The geometric interpretation of phasors, basic operations on phasors, and the derivation and integration of sinusoidal quantities are also explored. The lecture concludes with examples illustrating the application of internal impedance, voltage/current sources equivalence, and impedance/admittance in series and parallel.
