Chapter 6. Reactance
As I have indicated, there are only three types of passive components: resistors, capacitors, and inductors. Each of these impedes the flow of current, but each does so in a different way. We categorize them these three ways:
Resistance (designated by the symbol R) is the impedance to current flow that is presented by a pure (ideal) resistor. Resistance is measured in ohms. Resistance is directly related to the size of the resistor, but it is not a function of frequency and there is no phase shift associated with this impedance to current flow.
Reactance (designated by the symbol X) is the impedance to current flow that is presented by an ideal inductor or capacitor. Reactance is measured in ohms. Reactance is related to the ...
