Title: Impedance and Admittance Description: Explanatory video on the concepts of impedance and admittance for the analysis of sinusoidal steady-state circuits. Marín-Roig Ramón, J. (2019). Impedance and Admittance. http://hdl.handle.net/10251/120867 Automatic description: In this video, the professor from the Department of Electronic Engineering at the Polytechnic University explains the concepts of impedance and admittance. He begins by defining impedance as the ratio of the voltage phasor to the current phasor, and admittance as its inverse. He then emphasizes the importance of understanding how resistors, capacitors, and inductors function in the presence of alternating currents. The video addresses how to calculate impedances for these basic components and demonstrates the linearity of resistance with frequency, unlike the behavior of capacitors and inductors, which vary with frequency. The formulas for impedances are emphasized: in resistance, it is a constant, in coils, it is directly proportional to frequency, and in capacitors, it is inversely proportional. In addition, the course explains how variations in the magnitude and phase of impedances affect the amplitudes and phase shifts of currents and voltages. Finally, the course details how reactive components are used in circuit design as filters for different frequencies. The course concludes by showing how to calculate these measurements in an example circuit, summarizing what was learned in the analysis of circuit behavior at different frequencies.
