I've learned some concepts in my Electric Circuit Analysis course: Ohm's law KCL + KVL Voltage Division (derived from Ohm's law + KVL) Current Division (derived from Ohm's law + KCL) Y-Delta transformations Nodal Analysis (derived from Ohm's law + KCL) Mesh Analysis (derived from Ohm's law + KVL) So it seems that you can solve any circuit problem using nodal analysis and mesh analysis alone, right? Is there any benefit of the old method of solving circuits (using KCL & KVL)? Is there any benefit of using voltage division and current division when applying nodal and mesh analysis? I remember that when solving circuits through the use of KCL & KVL, you would sometimes need to apply voltage and current division. But because both divisions and both nodal & mesh analysis are derived from a combination of Ohm's law and Kirchhoff's laws, then the divisions are no longer necessary when solving a circuit using nodal/mesh analysis, right?
