- 4.1: AC Current Flow in a Good Conductor
- In this section, we consider the distribution of current in a conductor which is imperfect (i.e., a “good conductor”) and at frequencies greater than DC.
- 4.2: Impedance of a Wire
- The goal of this section is to determine the impedance – the ratio of potential to current – of a wire.
- 4.3: Surface Impedance
- Surface impedance is a materials property that characterizes the AC impedance of a material independently of the length and width of the material.
