Chapter 11 Balanced Three-Phase Circuits

Why a balanced three-phase circuit can be analyzed by an equivalent one-phase circuit? How to get all the unknowns (e.g. line voltage of the load) by the result of one-phase circuit analysis? Why the total instantaneous power of a balanced three-phase circuit is a constant?

Chapter 9 Sinusoidal Steady–State Analysis

circuits to (1) match impedances, and (2) eliminate dc signals. Ideal transformer is used in power circuits to establish ac voltage levels. MCM is used in transformer analysis, for the currents in various coils cannot be written by inspection as functions of the node voltages.

Chapter 7 Response of First-order RL and RC Circuits

Circuit model of a discharging RC circuit Consider the following circuit model: For t <0, C is open and biased by a voltage V g, while R 1 and R carry no current. For t >0, the capacitor voltage decreases and the energy is dissipated via R.
