Description

This lecture covers the concepts of impedances and admittances, focusing on the case of resistance and inductance in series. It introduces the concept of impedance as a form of resistance, using complex numbers in circuit theory. The instructor explains the definition of complex impedance and reactance, emphasizing the role of resistance and reactance in determining the impedance values. Additionally, the lecture delves into the application of complex numbers in representing impedance and the historical background of the term 'impedance'. The presentation includes examples of impedance calculations and the analysis of the capacitor case on a complex level.
