In this chapter, phasor algebra will be used to develop a quick, direct
method for solving both the series and the parallel ac circuits. The close
relationship that exists between this method for solving for unknown
quantities and the approach used for dc circuits will become apparent
after a few simple examples are considered. Once this association is
established, many of the rules (current divider rule, voltage divider rule,
and so on) for dc circuits can be readily applied to ac circuits.
