Lecture
This lecture covers the application of the Poynting theorem to complex phasors in the context of electromagnetism and circuits, focusing on the real and imaginary parts of power balance, power flow, and interpretation of sources. The instructor explains the calculation of power supplied by different components and the significance of reactive power. The lecture delves into the complex version of the Poynting theorem, emphasizing the cycle length and average power over one phase. Various concepts such as active power balance, power flow, and reactive power are discussed in detail.
