Thevenin Equivalent Circuit
- Thévenin’s theorem, as stated for sinusoidal AC circuits, is changed only to include the term impedance instead of resistance.
- Any two-terminal linear ac network can be replaced with an equivalent circuit consisting of a voltage source and an impedance in series.
- VTh is the Open circuit voltage between the terminals a-b.
- ZTh is the impedance seen from the terminals when the independent sources are set to zero.

The process used in AC analysis is the same with DC analysis.
