This volume is intended as a textbook for a first course in electrical engineering. It is divided into two parts, for a two-semester coverage.The first part deals with circuit elements, resistive circuits, circuit theorems, circuit topology, and the state-variable method. The presentation of the state-variable method is a special feature. The authors believe that the natural way to analyze RLC circuits is to use the state-variable method rather than second- or high-order ordinary differential equations. By choosing capacitor voltages and inductor currents in an RLC circuit as state variables,...
