Impedance in R-C Circuits
In a capacitive circuit, as in an inductive circuit, impedance is the resultant of phasor addition
of R and XC. Equation (8-11) is the mathematical representation for impedance in an R-C circuit.

Example:
A 50 W XC and a 60 W resistance are in series across a 110V source (Figure 7).
Calculate the impedance.
