IMPEDANCE Basic AC Reactive ComponentsFigure 8 Series R-C-L Impedance-PhasorEquations (8-12) and (8-13) are the mathematical representations of impedance in an R-C-Lcircuit. Because the difference between XL and XC is squared, the order in which the quantitiesare subtracted does not affect the answer.(8-12)ZR2(XLXC)2(8-13)ZR2(XCXL)2Example: Find the impedance of a series R-C-L circuit, when R = 6 W, XL = 20 W, and XC= 10 W (Figure 9).ES-08 Page 14 Rev. 0
