Ohm s Law, Voltage Divider, Mesh and Nodal Analyses. The difference with AC analysis is that complex impedances, known as phasors , must first be introduced to describe circuit components.
Analysis then continues, as in the DC case, to solve for any needed voltages or currents.
Finally, the needed V or I is converted from the phasor domain back to the time domain. Convert each circuit element to phasor representation. Analyze the circuit to find needed quantities. Use any appropriate method, as with a DC analysis. Convert needed quantities back to the time domain.
