In the chapter we shall study the properties of second-order circuits, i.e., circuits containing two energy-storage elements. Such circuits will, in general, be characterized by second-order differential equations

1. Nonlinear resistor A nonlinear resistor is an element whose voltage and current are related by a nonlinear equation
