2.1 Impedances

Passive devices include resistors, capacitors, and inductors. When these devices are used in a circuit, their most fundamental property is their impedance. The impedance Z of a resistor, capacitor, and inductor are expressed, respectively, below in Equations (2.1)–(2.3).

Figure 2.1 shows the ...
