Basic AC Reactive Components
Impedance is summarized below.
Impedance (Z) is the total opposition to current flow in an AC circuit.
The formula for impedance in a series AC circuit is:
The formula for impedance in a parallel R-C-L circuit is:
The formulas for finding total current (IT) in a parallel R-C-L circuit are:
where IC > IL , IT
where IL > IC , IT
