After transforming AC sources to Phasors and representing passive components in impedance, the AC circuits are equivalent to DC circuits, since the voltage (in Phasor forms, V ), the current (in Phasor forms, I), and the impedance (Z) are related by a linear equation, i.e., V=I-Z Thus, all DC circuit analysis methods are still applicable.
