The book contains two chapters that follow some selected topics Electrical Circuit's Theory: nonsinusoidal (distorted) and transient states. The latter is being investigated by different mathematical means.

Each of these chapters consists of three parts: the first one presents the basic theoretical concepts, the second one delivers solved numerical examples and cases studies that illustrate the application of the theoretical knowledge and finally, the third part challenges the readers to solve a large variety of proposed problems and applications.
