Chapter 4 Inductance and capacitance In the chapter we shall introduce some two-terminal element which have properties, which are quite different than those of the resistor These elements are the inductor and capacitor. The inductor and capacitor are passive elements, which are capable of storing and delivering finite amounts of energy.Chapter 4 Inductance and capacitance In the chapter we shall introduce some two-terminal element which have properties, which are quite different than those of the resistor.
