The practical limitations of Thevenin’s Theorem:
Many electrical circuits are only linear within a certain range of values. Therefore, Thevenin’s Theorem is only valid along this linear range.
The Thevenin’s equivalent has equivalent I-V characteristics only from the load’s point of view.
The Thevenin equivalent’s power dissipation is not strictly identical to the real system’s power dissipation. But power dissipated by an external resistor among two output terminals is identical, despite how the internal resistance is.
The limitations of the Thevenin theorem are:
Thevenin’s theorem can only be used in the analysis of linear circuits.
The power dissipation of the Thevenin equivalent is not identical to the power dissipation of the entire system.
