There are a variety of methods available to analyze complex electrical circuits, like Mesh Analysis, Nodal Analysis, or Kirchhoff's Circuit Laws.The problem is, when you're designing a DC power network you'll have a load whose value will change as your design process unfolds

Just as impedance extends Ohm's law to cover AC circuits, other results from DC circuit analysis, such as voltage division, current division, Thévenin's theorem and Norton's theorem, can also be extended to AC circuits by replacing resistance with impedance Thévenin's theorem is an electrical network analysis theorem or technique developed by the German scientist Hermann von Helmholtz and French engineer Léon Charles Thévenin , and states that: Any network or combination of sources and resistors with two terminals can be replaced by the equivalent circuit with a voltage source and a resistor in series Thevenin's Theorem Thevenin's Theorem states that any complicated network across its load terminals can be substituted by a voltage source with one resistance in series. This theorem helps in the study of the variation of current in a particular branch when the resistance of the branch is varied while the remaining network remains the same
